Injury News

Dolphins RB Jay Ajayi (concussion) was back participating in individual drills on Sunday, according to the Miami Herald's Armando Salguero. Ajayi remains in the concussion protocol, Salguero notes, but he's moving in the right direction again after possibly suffering a setback. There's still no reason to believe that Ajayi won't be fully cleared ahead of Week 1, but we'll continue to track the situation.

Broncos DE Derek Wolfe left Saturday's practice on a cart with what turned out to be a "really bad sprain," ESPN's Josina Anderson reported. Wolfe also said he suffered a ligament tear but reportedly hopes to be back to full strength by Week 1. Denver could use a relatively quick recovery after losing OLB Shane Ray to wrist surgery and DE Billy Winn to an ACL tear.

Dolphins RB Jay Ajayi (concussion) did not practice on Saturday after taking part in individual drills earlier this week. "That likely means he suffered a setback in stage 3 of the concussion protocol program," the Sun-Sentinel's Omar Kelly tweeted. It's more of an educated guess than a report from Kelly, but it's certainly concerning that Ajayi still hasn't been cleared nearly 2 weeks after sustaining the concussion.

Steelers WR JuJu Smith-Schuster suffered a concussion in Friday night's exhibition opener against the Giants. HC Mike Tomlin announced after the game that the rookie wideout had entered the league's concussion protocol after Smith-Schuster left the game for evaluation. We'll see how long he takes to recover.

Dolphins rookie LB Raekwon McMillan tore the ACL in his right knee in Thursday night's preseason opener against Atlanta. He had been working as the team's starter in the middle but will now obviously miss the 2017 season. The Miami Herald reports that Mike Hull will get the 1st shot to replace McMillan this year.

The Niners lost DT DeForest Buckner to an ankle injury in Friday night's preseason game at Kansas City. There's no initial word on the severity of the injury, but the team quickly ruled him out for the rest of the game. We'll pass along further details as they become available.

Dolphins QB Ryan Tannehill has decided to have his left ACL repaired and will miss the entire season, according to NFL Network's Ian Rapoport. That's not a surprising result, given that Miami paid QB Jay Cutler $10 million shortly after Tannehill re-injured the ligament earlier this month. Tannehill will have more than a year to recover from the surgery before the 2018 season. Cap numbers could leave Miami deciding whether to release the former #1 pick in the offseason, though.

The Lions got TE Eric Ebron back at practice Friday for the 1st time since he suffered a hamstring injury July 30, according to the Detroit News. He reportedly didn't spend the entire practice on the field, but there's no indication he suffered a setback with the hamstring. As long as Ebron continues to participate, he'll continue to represent upside in fantasy football drafts.

Vikings WR Laquon Treadwell missed Thursday night's preseason opener with a thigh injury. It's the 1st we've heard of it, but insider Chris Tomasson reports that Treadwell "missed more than a week of practice" with the issue. It's certainly not what he needs after a disappointing rookie season that included a broken finger, pulled hamstring and sprained ankle. Our model gives him a 66.2% chance of injury in 2017.

Patriots RB Mike Gillislee is dealing with a hamstring injury, according to insider Jeff Howe. He was also reportedly bothered by the hammy in OTAs. It's alarming considering his history. Gillislee missed all of 2014 after pulling a hammy and sat out 1 game last season with a hamstring issue. Our model gives him a 78.3% chance of missing time this year.

Redskins WR Josh Doctson is "day-to-day" with a "slight pull" of his hamstring, HC Jay Gruden said Monday. This doesn't sound like anything significant, but Doctson needs to stay on the field after missing most of his rookie season with Achilles trouble. We'll see how long the hammy keeps him sidelined. Our model gives Doctson a 34.3% chance of injury this year.

Rams WR Tavon Austin has missed the past 5 training-camp practices with a hamstring injury, according to ESPN's Alden Gonzalez. Austin also missed spring workouts after undergoing wrist surgery. HC Sean McVay labeled him "day-to-day," but the missed time is not ideal for a guy trying to learn a brand new offense with a young QB. Austin has missed 5 games through 4 NFL seasons and has a 52.4% chance of injury this season, according to our model.

The Jets have placed WR Quincy Enunwa (neck) on IR, ending his 2017 season. We still don't know much about the neck injury that he dealt with this spring and evidently aggravated on Sunday. But any issue with that part of the body is worrisome. We'll update his condition when we learn more.

Update: HC Todd Bowles said Monday afternoon that Enunwa has a bulging disk in his neck and is expected to be out 6-9 months. It's a big blow to a guy who's set to hit free agency next offseason.

Jets WR Quincy Enunwa exited Saturday's practice with a neck injury. "I know it's the same thing he hurt in the spring when he fell on it," HC Todd Bowles said afterward. "He hit his head [on Saturday] or he hit his neck or something went wrong when he fell." Enunwa reportedly fell to the turf after dropping a pass and stumbled when he tried to get up. He was eventually able to walk off the field under his own power. "[Trainers] didn't give me the nature of it," Bowles continued. "They just said it's the same thing he had in the spring. It wasn't severe, but it held him out a little while. I'll see the severity of it [this time] when I go inside [and speak to the trainers more]." We'll keep an eye on this one. Enunwa is in line to serve as New York's #1 WR this season. Our model currently gives him a just a 6.6% chance of injury.

Jets rookie S Jamal Adams suffered an ankle sprain in Thursday's practice and then sat out of Friday's workout. He told Newsday on Friday that he doesn't consider the injury "severe," but we'll see how long the 1st-round pick stays sidelined.

Titans HC Mike Mularkey labeled WR Corey Davis "week to week" with his hamstring injury. "We're just going to play it by ear and see how it is," Mularkey added. "He'll be out at least a week, maybe longer." Davis is obviously dealing with something more than a minor injury. Barring a setback, he should be ready for the start of the regular season. But the missed time is no good for a rookie.

Broncos S T.J. Ward hobbled off the field Friday with a right hamstring injury, according to the Denver Channel. The team didn't know after practice how serious or mild the injury might be, HC Vance Joseph said. So we'll await further word on the situation.

Colts WR Donte Moncrief is "day to day" with a "mild" AC sprain in his shoulder, HC Chuck Pagano said on Friday. Moncrief missed 5 games last year with a broken shoulder blade, although it doesn't seem like this is at all related. Our model has Moncrief with a 27.8% chance of injury this season.

As we continue to await Miami's decision on whether to have QB Ryan Tannehill undergo surgery on his left knee, we've at least learned the best possible case for the former 1st-round pick. According to ESPN's Jeff Darlington, the non-surgical option is to have Tannehill rest for 6-8 weeks. The regular season kicks off in a little more than 5 weeks, so consider Tannehill a long shot to play in the opener. He'll likely miss at least the first 2-3 games. And, of course, it's still possible he's done for the year.

Redskins TE Jordan Reed spoke to the media on Thursday for the 1st time since we learned of his toe issue. He revealed that the toe bothered him all last year. It felt better this spring but became a problem again when he had stem-cell treatment. "That kind of flared it up a bit on me," Reed said. "Now I'm just letting it calm down before I get out there." The specialist he visited earlier this week recommended only rest. "I've just gotta take my time, let it heal and strengthen up, then get back out there," Reed added. He remains the biggest injury risk at his position.
