Patriots WR Phillip Dorsett suffered a hamstring injury early in Sunday's game against the Redskins and will not return. We'll look for an update on the severity of the injury. Dorsett's absence leaves rookie Jakobi Meyers as New England's #3 WR.

Colts RB Marlon Mack's status for tonight's game against the Chiefs will be a game-time decision, and NFL Network's Ian Rapoport reports that the "team will be cautious." That's worrisome for the fantasy outlook on Mack, who missed practice Wednesday and Thursday before returning to a full workout Friday. If you're waiting on him, then you'll need to have Nyheim Hines, Jordan Wilkins or a decent option from the Chiefs or 49ers available as a fallback.

Patriots RB Rex Burkhead (foot) has been downgraded to out for Sunday's game against the Redskins. He was active with this injury last week but got just 1 touch. Burkhead will now try to get ready for Thursday night's game vs. the Giants. We'll see if rookie RB Damien Harris is active for the 1st time this season on Sunday, but RBs Sony Michel and James White will handle the majority of New England's backfield work.

Colts RB Marlon Mack (ankle) is listed as questionable for Sunday night's game against the Chiefs. He sat out Wednesday and Thursday's practices but was a full-go Friday. HC Frank Reich said early in the week that Mack wasn't medically ruled out of last week's game, so we're expecting Mack to play on Sunday night.

Patriots RB Rex Burkhead (foot) is listed as questionable for Sunday’s game against the Redskins after a limited week of practice. It’s the same boat he was in last week before playing just 19% of the offensive snaps and registering only 1 touch. Burkhead can’t be trusted in fantasy lineups until we see that he’s healthy.

Rams WR Brandin Cooks left in the 4th quarter of Thursday night's game against the Seahawks to get checked for a concussion and didn't return. We haven't yet seen confirmation that Cooks was concussed, but it looked like he was briefly knocked out on the field. We'll look for updates on his status. Cooks has 10 days to get cleared for Week 5's meeting with the 49ers. His absence would elevate WR Josh Reynolds to #3 on the depth chart.

Colts RB Marlon Mack (ankle) missed practice again on Thursday. It's worth noting that he played back in Week 3 despite only getting in a limited practice on Friday with his calf injury. And HC Frank Reich said that Mack wasn't medically ruled out of last week's game. Mack still has a shot to play against the Chiefs on Sunday night, but check back tomorrow for another update.

Colts HC Frank Reich said Monday that RB Marlon Mack wasn't knocked out of Sunday's loss to the Raiders by his ankle injury. It sounds like the Colts just opted for more Nyheim Hines in catch-up mode. That obviously adds game-script risk to Mack going forward. But it at least sounds like he'll be available for Sunday night's game in Kansas City (where game script could be a problem).

Colts RB Marlon Mack suffered an ankle injury in the 4th quarter of Sunday's game against the Raiders. He was deemed questionable to return but never did. We'll look for an update on his status.

Patriots RB Rex Burkhead (foot) is active for today’s game against the Bills. He was limited in practice all week and was reportedly a game-time decision, so he clearly comes with risk in Week 4 fantasy lineups.

NFL Network's Ian Rapoport calls Patriots RB Rex Burkhead (foot) a game-time decision for today's tilt in Buffalo. Burkhead was limited in practice all week, but as usual with New England, we've heard nothing about the injury. We'll get the Patriots' inactives around 11:30 am ET this morning. Burkhead's absence would be a nice boost for RBs Sony Michel and James White.

Patriots RB Rex Burkhead (foot) was limited in practice all week and is listed as questionable for Sunday’s game against the Bills. We’ve heard nothing to suggest that he’s in danger of missing this game, but check the inactives at 11:30 am ET on Sunday to make sure Burkhead is suiting up.

Colts RB Marlon Mack (calf) is active for today’s game against the Falcons. He only got in a limited practice on Friday and was reportedly a game-time decision, so he’s clearly not at 100%. Consider Mack a risk/reward RB2 in Week 3 fantasy lineups.

ESPN's Adam Schefter calls Colts RB Marlon Mack (calf) "likely" to play against the Falcons today. "But team wants to test him in pre-game warmups before making any final decision on his status," Schefter adds. Mack only got in a limited practice on Friday, although the Indianapolis media always seemed optimistic about his Week 3 availability. We'll get his official game status by noon ET. If active, Mack will be a risk/reward RB2.

The Browns have placed LB Christian Kirksey on IR with his chest injury. Kirksey is reportedly still getting opinions on how to treat the injury, which is believed to be a torn pectoral muscle

Colts RB Marlon Mack (calf) is questionable for this weekend's game against the Falcons. He returned to a limited practice on Friday after missing the first 2 workouts of the week. The Indianapolis media seems to be optimistic about Mack's chances of playing vs. Atlanta. We'll get his official status by noon ET on Sunday. If active, Mack will be a risk/reward RB2. If not, Jordan Wilkins figures to serve as the Colts' lead back, with Nyheim Hines also playing an increased role.

Browns OLB Christian Kirksey will miss at least Sunday night's game against the Rams with a chest injury he suffered in Week 2, Cleveland.com reports. HC Freddie Kitchens said Thursday that they're still evaluating the injury and wouldn't specify. The concern is that Kirksey tore a pectoral muscle. Cleveland.com reports he might need surgery. We'll keep an eye on Kirksey's situation. Rookie Mack Wilson will start in his place against the Rams and is worth adding in deeper IDP leagues. Kirksey was playing full-time snaps before the injury, and Wilson enjoyed a strong preseason.

Jaguars WR Chris Conley is questionable to return to Thursday night's game against the Titans with what the team announced as an ankle injury. He rolled his ankle and hyper-extended his knee on the same play. We'll update Conley's status when we learn more.

Update: Conley returned later in the 2nd quarter.

Colts RB Marlon Mack (calf) missed practice again on Thursday. He's now in real danger of missing this weekend's game against the Falcons -- although insider George Bremer believes there's still a "decent chance" Mack plays. We'll get another update on his status tomorrow, but fantasy owners need to be making backup plans. Jordan Wilkins figures to serve as the Colts' lead ball carrier if Mack sits.

Colts RB Marlon Mack was listed as a non-participant on Wednesday with a calf injury. The team only had a walkthrough, so it's an estimate of Mack's participation. This obviously bears monitoring over the next couple of days, though. Mack's absence would leave Jordan Wilkins as the Colts' lead ball-carrier, with Nyheim Hines potentially playing an expanded role.
