Steelers DE Stephon Tuitt will miss the rest of the season after suffering a torn pectoral muscle in Sunday night's win over the Chargers, according to ESPN's Chris Mortensen. Tuitt will have surgery and should be ready for the 2020 season.

The Giants placed WR Sterling Shepard in the concussion protocol Monday morning for the 2nd time this season. Shepard didn't leave Sunday's loss to the Vikings but exhibited symptoms at team headquarters Monday morning. Shepard previously missed the Week 2 loss to Buffalo with a concussion.

Giants RB Saquon Barkley suffered a high right ankle sprain in Sunday's win over the Buccaneers, according to NFL Network's Ian Rapoport. The injury is expected to cost Barkley at least the "next several weeks." Wayne Gallman looks like the lead back while Barkley is out.

Steelers FS Sean Davis landed on IR this week after tearing the labrum in his right shoulder. It's not yet clear whether he'll need surgery, but the Pittsburgh Post-Gazette reports that Davis isn't expected to miss the rest of the season. Davis previously had surgery for a torn shoulder labrum following the 2016 season, though we haven't seen which shoulder was affected in that case.

Jaguars MLB Myles Jack left Thursday night's game early with a concussion. He'll now need to pass through the league concussion protocol before returning. It appears to be the 1st known concussion of Jacks' NFL career.

Colts LB Darius Leonard is in the league protocol following Sunday's game against the Titans. HC Frank Reich told reporters Monday that Leonard developed symptoms after the game. We'll see if he can make it through the league protocol in time for Sunday's home date with the Falcons.

The Browns have ruled S Damarious Randall out for Monday night's game against the Jets after he arrived at team facilities Saturday with a concussion, NFL Network's Ian Rapoport reports. It's at least the 2nd concussion of his career. Randall suffered 1 in the 2017 preseason while with the Packers.

Buccaneers DE/OLB Jason Pierre-Paul has been out since a spring car accident caused a neck fracture. ESPN's Jenna Laine reports that doctors have cleared him to begin rehab. She adds, however, that there remains no timetable for his return to the field and that the Bucs "absolutely will not rush this."

ESPN's Jenna Laine reports that Buccaneers RB Ronald Jones returned to the practice field Friday. Jones had been out since hyperextending his left knee in the 2nd preseason game. But he missed less than a week. The injury doesn't seem like something we need to worry about. Jones' slow development, on the other hand, looks like a significant issue.

Giants WR Golden Tate missed practice Sunday, and the team announced that he's in the concussion protocol. Expect the Giants to be conservative with the veteran, but this appears to be his 1st known concussion as a pro. Tate, of course, is suspended for the 1st 4 weeks of the regular season under the league's PED policy.

Chargers S Derwin James will have surgery on his right foot after suffering a stress fracture to the 5th metatarsal, according to NFL Network's Mike Garafolo. Foot specialist Robert Anderson will perform the surgery, and James is then expected to miss about 3 months. That does, at least, keep him a candidate to come off IR late in the year.

The Jets have lost ILB Avery Williamson for the season after he suffered a torn right ACL in Thursday night's exhibition game against the Falcons, according to multiple outlets.

The Chargers announced Friday that S Derwin James will miss an unspecified amount of time after suffering a stress fracture in the 5th metatarsal of his right foot. ESPN's Josina Anderson reports that James has talked to foot specialist Dr. Robert Anderson and is "determining what next steps he wants to take." That likely means he's considering whether to have surgery, which would probably extend his return timeline. This will be a situation to watch concerning 1 of the NFL's top young defensive talents.

We already knew that Broncos WR Emmanuel Sanders had surgery in December to repair his torn left Achilles' tendon. Mike Klis of 9News in Denver reported Monday, though, that Sanders also had "tightrope" surgery on his right ankle. That operation reportedly treated an injury that Sanders suffered back in October 2017 and that dogged him throughout last season. "Tightrope" surgery can be used to repair high-ankle sprains, according to the Souther California Orthopedic Institute. Sanders blamed that injury for causing his Achilles' tear. No one can know how true that might be, but this operation sounds like a positive for Sanders' health heading into 2019 -- rather than a knock on his outlook.

Eagles TE Dallas Goedert came away from Thursday night's preseason opener with a calf injury. The team announced Saturday that he'll sit out the final 3 exhibitions and is currently "week to week," per multiple reports. According to the Philadelphia Inquirer's Jeff McLane, the injury isn't considered serious. Philly expects Goedert to return in time for the regular-season opener.

Niners RB Jerick McKinnon returned to practice this week for the 1st time since tearing his right ACL last summer. The knee has not responded well to the work, though. "He'll be shut down for a while," according to Matt Maiocco of NBC Sports Bay Area. The lack of a timetable is worrisome, especially for a RB on a team with Tevin Coleman and Matt Breida ready to go.

The 49ers will be without DE Nick Bosa for an undetermined span after he sprained his right ankle in Wednesday's practice. An MRI confirmed the injury, according to NFL Network's Ian Rapoport. It's not yet clear how long the team expects Bosa to be out.

Cowboys DE Robert Quinn suffered a left hand fracture in practice Tuesday and will miss the rest of August, according to multiple reports. Quinn will have surgery on the hand but is expected to return for the regular season.

HC Pete Carroll confirmed Monday that MLB Bobby Wagner had platelet-rich plasma therapy on 1 of his knees over the weekend, according to multiple sources. Carroll said Wagner has had the procedure "a couple of times" previously and found success. Other Seahawks players have also sought the treatment in recent seasons. Wagner's expected to sit out the team's preseason opener Thursday but could return for the 2nd exhibition. The situation doesn't appear likely to affect his regular-season availability.

The Colts will miss DE Jabaal Sheard for an unspecified amount of time because of a knee injury. Fox59's Mike Chappell reports that the DE recently had surgery on a knee issue that has kept him out since the 2nd day of training camp. It's not yet clear what injury Sheard suffered or how long he'll be out. We'll watch for those details.
