Injury News

49ers TE George Kittle separated his shoulder in Thursday night's preseason game. The good news is that an MRI revealed no tears or structural damage," according to NFL Network's Ian Rapoport. "Not serious," Rapoport added. Kittle still figures to miss practice time, though, and we can't consider him a lock to be ready for the start of the season. We'll keep an eye on his rehab. It's worth noting that, despite missing just 1 game last year, Kittle appeared on the injury report with hamstring, calf, hip, chest, back, elbow and ankle issues.

The initial diagnosis on Redskins RB Derrius Guice's injured knee is a sprained MCL, according to NFL Network's Ian Rapoport. The rookie is undergoing an MRI today to get more details. The severity of the sprain will determine exactly how long he's sidelined. We'll pass along another update when we get one. Rob Kelley played ahead of Samaje Perine in Thursday night's preseason opener, making him the favorite to serve as Washington's early-down back if Guice misses regular-season time.

Steelers WR Antonio Brown's chiropractor revealed on Instagram Monday that Brown is dealing with a hip flexor issue. It was previously reported as a quad injury. Brown has been sidelined for about a week now and won't play in Pittsburgh's preseason opener -- but he did re-join the team on Tuesday after being in Pittsburgh to have that injury re-evaluated. We're still not worried about Brown at this point but would like to see him back on the field by next week.

Chiefs S Daniel Sorensen will need surgery on an unspecified knee injury and "will miss the first part of the season," according to ESPN's Adam Schefter. Sorensen has been working as a starter so far in training camp. We'll see what happens when he returns. We'll also keep an eye out for further details on his injury.

Rams TE Gerald Everett is sidelined with a shoulder sprain, HC Sean McVay said. "You guys see him out here where he had a little splint. We’re going to be smart with him," McVay said. "So, he’ll probably be doing rehab and different things like that for at least the next week or so ... Fortunately, it’s not something right now that we felt like had to get fixed, but until you really go through that process you never know how it’s truly going to respond.” This doesn't sound like a serious issue, although McVay does make it seem like the team doesn't know exactly how long Everett will be out. We'll keep an eye on this one.

The Lions on Monday activated DE Ezekiel Ansah from the PUP list, where he had been since the start of training camp. The team officially has yet to disclose his injury, but we're assuming it's related to his spring knee surgery. Ansah is set to play 2018 under the franchise and then hit free agency in the spring.

The Bills on Sunday activated WR Zay Jones from the non-football injury list. The team website reports that he'll start out in a non-contact jersey as he practices for the 1st time since mid-May knee surgery. Jones also had surgery for a torn shoulder labrum after the season. He'll have much to prove after an ugly debut campaign following his 2nd-round selection in the draft.

Patriots RB Sony Michel suffered a knee injury in practice Wednesday that will require a "procedure," according to Jeff Howe of The Athletic. The operation is expected to keep Michel out for the entire preseason and might cost him the beginning of the regular season. We'll keep an eye out for further details on the injury and, of course, watch his recovery.

Update: According to ESPN's Mike Reiss, the procedure drained fluid from Michel's knee. He echoed Howe's report that the recovery isn't expected to reach far into the regular season -- if it does at all.

Texans WR Keke Coutee is expected to miss "a few weeks" with a hamstring injury, according to the Houston Chronicle. Coutee had a buzzy spring and looked like the favorite for Houston's #3 WR job. But this injury hurts his chances of making an early-season impact.

Titans S Johnathan Cyprien tore his left ACL in Wednesday's practice and will miss the coming season, the team announced Thursday. Cyprien is entering his 2nd season with Tennessee. He lost 6 games to a hamstring injury in 2016. The Titans look thin on experience at the position after letting S Da'Norris Searcy walk in the offseason and might look to add from a plentiful free-agent market at safety. Cyprien will turn 29 next July.

Patriots WR Jordan Matthews is dealing with what NFL Network's Ian Rapoport calls a "significant" hamstring injury. Matthews went down in practice on Sunday and hasn't been back on the field since. He had been considered the favorite to step in during Julian Edelman's 4-game suspension, but this injury throws a wrench in those plans.

Seahawks WR Doug Baldwin had a "sore knee" when he arrived at training camp and will be sidelined "a couple weeks," HC Pete Carroll said Tuesday. "It's a little bit of a problem," Carroll added. We'll look for more details on Baldwin's injury, but it doesn't sound like he's in jeopardy of missing the start of the season, which is still 5-and-a-half weeks away.

Jets RB Elijah McGuire will undergo surgery on his broken foot and is expected to miss 3-6 weeks, ESPN's Adam Schefter reports. The short end of that timetable would have him back in late August; the long end would keep him out through the season opener. Foot injuries are notoriously tricky to return from, so we're considering McGuire questionable at best for Week 1.

Seahawks DE Frank Clark had wrist surgery in June, according to the Tacoma News Tribune. Clark has participated on a limited basis in training-camp practices so far, but it's not yet clear when he'll be a full go. Clark said on Twitter that he played through broken bones in both hands last season, eschewing the in-season surgery option because he didn't want to face the 8-10 week recovery timeline.

The Browns placed S Jabrill Peppers on the PUP list to begin training camp, as the 2nd-year player deals with a groin strain. We'll see how long the issue keeps him out. Peppers faces potential competition from Derrick Kindred for his starting job after a lackluster rookie season.

Vikings RB Dalvin Cook has decided to practice with no brace on his surgically repaired left knee. He told the Pioneer Press that he chose to test the knee without a brace before camp and got a thumbs up from the training staff to go ahead. Cook tore the ACL in that knee in Week 4 last season but appears to be back to full strength heading into the 2018 season.

Texans RB D'Onta Foreman will open training camp on the active/PUP list as he continues rehabbing last November's torn Achilles. Foreman has been setback-free so far, and GM Brian Gaine said earlier this offseason that he expects Foreman to be ready for Week 1. Still, the 2nd-year back will need to get on the field quickly if he wants to push RB Lamar Miller for early-season touches.

Redskins RB Chris Thompson is ready for the start of training camp after going down with a broken leg last November. "I'm feeling pretty good right now, I will start practicing w/ the guys from day one but just taking it slowly," he said Monday. "The focus is to really be ready by that first regular season game." That broken leg shouldn't be a factor this year, but Thompson's lengthy injury history remains a concern.

Patriots WR Malcolm Mitchell underwent surgery on his knee on Monday, according to the Providence Journal's Mark Daniels. It's presumably the same right knee that he injured late in 2016 and caused him to miss the entire 2017 season. Now Mitchell's 2018 campaign "looks to be in jeopardy," Daniels writes.

Update: The procedure on Mitchell's knee was "aimed at hoping to accelerate healing," according to NFL Network's Ian Rapoport.

Chiefs RB Spencer Ware (knee) is ready for the start of training camp, HC Andy Reid said. Ware missed the entire 2017 campaign with a torn PCL and LCL in his right knee. He was set to open last season in a committee with Kareem Hunt but obviously returns as a pure backup.
