Lions C Frank Ragnow left Friday night's preseason game against the Bills with a worrisome-looking leg injury. NFL Network's Ian Rapoport, however, reports that Ragnow sustained only a minor ankle sprain. With 2 weeks until the season begins, this doesn't seem like an issue that should alter fantasy football outlooks for others on the Detroit offense. Treat RB Kerryon Johnson and/or QB Matthew Stafford as you were planning.

NFL Network's Ian Rapoport reports that the Lions are releasing RB Theo Riddick. The timing of the move is surprising, but it follows offseason rumors that Riddick might be on the roster bubble. Riddick ranked 2nd on the team in targets last season (74) despite missing 2 games. He has averaged 4.4 receptions per game over the past 4 seasons. Riddick's departure raises the target ceiling for breakout candidate Kerryon Johnson.

Lions RB Kerryon Johnson said he's back to 100% after a November knee injury ended his rookie campaign. He didn't need surgery and will get in a full offseason of work. Johnson will need to hold off RB C.J. Anderson for work but has breakout potential in new OC Darrell Bevell's run-focused offense.

The Lions have reached a 1-year deal with RB C.J. Anderson, according to ESPN's Adam Schefter. That supports HC Matt Patricia's recently stated plan of continuing to deploy a backfield committee. Anderson joins a group that will also return Kerryon Johnson, Theo Riddick and Zach Zenner (who got a new 1-year deal). Anderson came on with the Rams at the end of last season after doing next-to-nothing with the Panthers. L.A. opted for youngster Malcolm Brown, however, behind Todd Gurley. Anderson threatens to take goal-line carries from Johnson, though the 2018 rookie remains the highest-upside RB in Detroit. This will be 1 of the more interesting backfield's to project over the next 2 months.

Lions HC Matt Patricia suggested that his team will continue to deploy a committee backfield in 2019, not wanting to overwork RB Kerryon Johnson. "I think it’s a position-specific thing where those guys, they take a lot of hits,” Patricia said. “They’re in those situations a lot where their bodies are taking some pounding so you want to be conscious of how many plays they’re getting, especially early on in the year." Patricia comes from New England, where the Patriots have long utilized multiple RBs. The Lions return RBs Theo Riddick and Zach Zenner behind Johnson and might still add to the position in free agency or the draft. There are, of course, very few every-down backs in the NFL. So Johnson still has a shot to flirt with RB1 value in his sophomore campaign under run-loving OC Darrell Bevell.

The Lions have named Darrell Bevell their OC. The run-heavy play-caller fits exactly what HC Matt Patricia wants his offense to do. Bevell has spent 12 seasons as an NFL OC -- 5 in Minnesota, 7 in Seattle -- and had 7 teams finish top 10 in rushing attempts and 7 finish top 10 in rushing yards. Only 3 of Bevell's units ranked inside the top half of the league in passing attempts or yards. His arrival is good news for Kerryon Johnson and troublesome for Matt Stafford, Kenny Golladay and Marvin Jones.

The Lions and OC Jim Bob Cooter have agreed to "mutually" part ways, according to NFL Network's Ian Rapoport. A favorite of the Draft Sharks podcast, Cooter's tenure in Detroit got off to a nice start. But he was at the controls of 1 of the most disappointing offenses in the league in 2018, with the Lions finishing 24th in total yards and 25 in points. With a nice core in Matt Stafford, Kerryon Johnson, Kenny Golladay and Marvin Jones, this unit is capable of a big bounce back in 2019.

Lions RB Kerryon Johnson has been placed on IR with the knee injury he suffered back in Week 11. It ends promising rookie season that saw him average 5.4 yards per carry and haul in 32 balls. We still don't have any details on Johnson's injury, but he should be fine for the offseason program. Zach Zenner, LeGarrette Blount and Theo Riddick will close out the year in Detroit's backfield. Zenner led the way with a 46% snap rate, 10 carries and 4 targets in last week's loss in Buffalo.

Lions RB Kerryon Johnson (knee) is out for Sunday’s game against the Bills. The rookie has yet to practice since going down and has no timetable for return. Detroit’s backfield devolved into a 3-man committee last week with LeGarrette Blount, Theo Riddick and Zach Zenner. It’s a situation best avoided in Week 15 fantasy lineups.

Lions RB Kerryon Johnson (knee) is out for Sunday’s game against the Cardinals. He remained sidelined all week and still has no timetable for return. LeGarrette Blount will continue operating as Detroit’s lead ball-carrier, with Theo Riddick handling pass-catching duties.

Lions RB Kerryon Johnson (knee) remained sidelined for Wednesday's practice. Don't expect him back for this weekend's game against the Cardinals. With Johnson out the past 2 weeks, LeGarrette Blount has carried 35 times and seen 2 targets. Theo Riddick has tallied 10 carries and 11 targets.
