Bills RB C.J. Spiller is ecstatic about his chance to expand on his terrific numbers of 2012. He told the NFL Network on Wednesday that he has been going all-out since to get on board with new HC Doug Marrone's system. When asked about a potential time-share with teammate Fred Jackson, the Bills back was understandably coy. “We haven't really sat down and discussed how we're gonna split carries,” he said. “It's good to have 2 good RBs on the team. We're very fortunate to have 2 great RBs to go out there and make plays.” We aren't too concerned that Jackson will bite heavily into Spiller's upside this year. Marrone can't afford to let the phenom waste away on the sidelines after the 25-year-old averaged 6 yards per carry last season. He's a rock-solid RB1 worth nabbing with a mid-to-late 1st-round fantasy pick.

The Bills plan to feed RB C.J. Spiller the rock the rest of the way.  "CJ will get it as much as he wants," HC Chan Gailey said on Monday.  Spiller's usage has been frustrating this season, but Buffalo really has no choice now with RB Fred Jackson sidelined.  In his 2 full games with Fred Jax out earlier this year, Spiller totaled 300 yards and 2 TDs.  He should be locked into fantasy lineups for the remainder of the season.

Bills HC Chan Gailey plans on splitting backfield snaps 60:40 in favor of C.J. Spiller over Fred Jackson the rest of the way.  We'd like to see something closer to 70:30, but at least Spiller remains the lead back.  Fred Jax actually played more snaps against the Colts on Sunday (32 to 29), but Spiller out-touched him 15-7.  We're expecting a similar 2-to-1 split the rest of the way.  That'll make Spiller a borderline RB1 in fantasy, and Jackson a low-end RB2.

Bills HC Chan Gailey announced RB C.J. Spiller as his starter going forward.  That's despite the expected return of RB Fred Jackson from that concussion.  Gailey made it clear that Fred Jax will get his looks too, but it sounds like the team is ready to commit to getting the explosive Spiller about 20 touches per game.  That makes him a must-start in fantasy going forward.  Jackson will be a lower-end RB2.

Despite being the most electric player on the field in Sunday's game against the Cardinals, Bills RB C.J. Spiller will continue to share backfield duties with RB Fred Jackson.  “I know he needs to touch it as much as we possibly can have him touch it," HC Chan Gailey said of Spiller Monday.  "But Fred is another big play guy as well.  But I think the issue is how do we get both guys more touches.”  Jackson played 40 snaps and received 21 touches on Sunday.  Spiller played 31 snaps and finished with 16 touches.  But Spiller out-produced Jackson 110 yards to 83.  We're expecting him to see an increased role moving forward, but Fred Jax isn't going away.  That'll prevent Spiller from entering RB1 territory.

Bills RB C.J. Spiller (shoulder) is active for today's game against the Patriots.  It's a major surprise after he appeared to suffer a major injury a week ago.  We're expecting Spiller to play a limited role today, especially since RB Fred Jackson is active.  Spiller is just a low-end RB3 or flex option.

Bills RB C.J. Spiller (shoulder) is listed as questionable for this weekend's game against the Patriots.  He put in limited practices on Thursday and Friday and is shaping up as a game-time decision.  Even if Spiller is active, though, he figures to play an extremely limited role.  We'd keep him on fantasy benches.

Bills RB C.J. Spiller (shoulder) put in a limited practice on Thursday.  It's confirmation that Spiller's injury is not serious, although we'd still bet against him playing this weekend.  “I’m just taking it day by day,” Spiller said. ”We’ll see how it goes. The main thing we don’t want to do is rush it. It’s Week 4 and we’ve got 16-plus if we get to the postseason so we’ll do day by day and see what Sunday holds.”  Check back tomorrow for another update.

Bills RB C.J. Spiller says he has full range of motion in his injured shoulder.  He's not even wearing a sling.  Spiller did admit that he's dealing with some pain and swelling, but he says he has a chance to play against the Patriots this weekend.  While we'd bet against that -- especially if RB Fred Jackson is ready -- a Week 5 return looks plenty doable for Spiller.  He really dodged a bullet here.

NFL insider Jason La Canfora passes along word that Bills RB C.J Spiller’s injury is a sprained A/C joint, and not a separated shoulder. It’s excellent news for Buffalo fans and fantasy owners alike, as the injury comes with a 1-2 week timetable, per La Canfora. However, he also Tweeted that Fred Jackson “should” play Sunday against New England. Jackson’s return would come a week or two earlier than expected, and it’d throw some cold water on veteran Tashard Choice’s short-term value. Meanwhile, fantasy owners should take a wait-and-see approach with Spiller. When healthy, we’re optimistic he’ll lead the backfield attack over Jackson.

Here's what Bills HC Chan Gailey said about injured RB C.J. Spiller after Sunday's game against the Browns: "I don't believe it's long, long term. If he misses a week, that's long for me. I think he's going to be out for sure this week, and then we'll see where he goes from there. He's out for a week or two, but I don't know how extensive it is." Gailey also confirmed that Spiller's collarbone is not broken. This sounds like a best-case scenario, although we should get a better idea of how long Spiller will be out after additional testing on Monday.  He could be in a race with RB Fred Jackson (knee) to see who can get back first.  In the meantime, RB Tashard Choice will serve as Buffalo's lead back. 

Bills RB C.J. Spiller suffered a separated shoulder during today's game against the Browns.  He'll undergo an MRI on Monday to get a better idea of how bad the damage is.  A separated shoulder is better news than something like a broken collarbone.  Check back tomorrow for an update on Spiller's status.

Bills RB C.J. Spiller appeared to suffer a shoulder injury during Sunday's game against the Browns.  He had to be carted off the field.  It didn't look good.  We'll pass along an update when we get one.

Update: Spiller has officially been ruled out for the rest of the game.  Tashard Choice is operating as the lead back.

Bills QB Ryan Fitzpatrick is calling for a breakout season from RB C.J. Spiller.  "C.J. is a completely changed man," Fitzpatrick said. "It's been apparent from day one of this off-season. I think the biggest thing with what he did at the end of the year last year, was he got his confidence. You just see how comfortable he is in this system now... I think he's ready to make a big jump. I think mentally he's made a big jump in the last year. With his confidence level where it is right now, we expect big things out of him this year. He really showed last year what he can do."  Spiller's furious finish to 2011 has been well-documented.  And by all accounts, he's had an impressive offseason.  His fantasy upside will hinge on just how many touches the Bills get him in their committee attack.  RB Fred Jackson wasn't half-bad last year.  We'll be keeping a close eye on the situation this summer.

Bills HC Chan Gailey praised RB C.J. Spiller for his pass-blocking ability.  That was the biggest knock against him during his 2010 rookie campaign, and it may have limited his playing time early last season too.  “He can do a lot of things blocking,” Gailey said. “He’s gotten better at his blocking from the previous year.”  Pro Football Focus actually graded Spiller as the 5th-best blocking RB in the league last year, although teammate Fred Jackson finished 1st.  Both guys have emerged as well-rounded RBs who can play all over the field.  Buffalo is looking to get Spiller and Fred Jax on the field together in 2012.  But it's tough to imagine either guy getting enough touches to be anything more than a RB2 in fantasy.

Although Bills HC Chan Gailey believes that RB C.J. Spiller could be a workhorse back, Gailey confirmed that Spiller and RB Fred Jackson will split touches in 2012.  "I don't see any reason he couldn't carry 20-25 if he needed to," Gailey said of Spiller. "But he’s a valuable, versatile player. He can play wideout. We’re fortunate to have two very good backs. I’m going to try to make sure we keep them fresh and wear ‘em out at the same time. Does that make sense? But you want them to be on the field doing something, running routes, creating a threat for the defense."  We're betting the Bills have both Spiller and Jackson on the field together quite a bit this coming season.  But there's only 1 football to go around, so neither guy is likely to be anything more than a low-end RB2.

Bills GM Buddy Nix had high praise for RB C.J. Spiller in his season-ending press conference.  "Everyone's been surprised, I guess, about C.J. except us," Nix said. "We always knew what we had. The opportunity is what he needed and he got it when Fred [Jackson] got hurt. I'm one of the few who thinks C.J. can run inside and be a workhorse kind of back. I think he can run inside the tackles. He's stronger than you think he is."  After Jackson went down in Week 11, Spiller averaged 18 touches per game.  He ranked 4th among RBs in fantasy points over the final 6 weeks.  Buffalo's backfield will be a situation to monitor closely this offseason.  Fred Jax was one of the top backs in the NFL before going down, and he'll likely retain lead duties.  Spiller certainly earned a bigger workload though.  It could end up being closer to a 50-50 split than most people think.

Bills RB C.J. Spiller had a career-day against the Dolphins on Sunday.  Despite receiving just 12 carries, he busted off a career-high 91 yards and a score.  A large chunk of that damage came on a 24-yard TD run in the 1st quarter.  It was an impressive rushing performance against a Miami squad that entered the day having allowed just 4 TDs and 3.5 yards per carry to opposing backs.  But Spiller might have been even better in the passing game.  He hauled in a team-high 9 balls on 11 targets for 76 yards and another TD.  Those marks were all personal-bests.  Spiller has really stepped up his game since taking over for the injured Fred Jackson.  In 4 starts, he's averaging 14 carries for 69 yards per outing, plus another 30 receiving yards on 4.5 catches.  He gets a tough Denver defense in Week 16.  But Spiller's workload and explosive ability will make him worth keeping in fantasy lineups.

While Bills HC Chan Gailey said that RB C.J. Spiller did just "OK" in rushing for 55 yards on 19 carries against the Jets last weekend, he did like Spiller's pass protection and ball security.  Those were 2 of the biggest knocks against him last season.  "One thing that really was improved was his pass protection," Gailey said. "He did a much better job of taking on a couple guys and chipping at a couple guys and he secured the ball the whole day. Those were the two big things in the offseason that he needed to improve on and he did better at that."  Spiller continues to struggle between the tackles, but he's locked-in as Buffalo's lead back.  Expect another 18+ touches against the Titans this Sunday.
