Carroll, who signed with the Cowboys this offseason, could be subject to league discipline due to this transgression.
A second-round pick of the 2014 draft, Niklas' career has been derailed by a deluge of injuries. In advance of the event, a sports hernia was discovered at the Combine that required surgery. Then, in just his third spring practice with the Cardinals, he broke a finger in his left hand. After suffering through two severe ankle sprains in the first half of his rookie season, Niklas was mercifully placed on IR, ending his campaign. As a sophomore, he avoided the injury bug, yet he managed just four receptions for 33 yards and two touchdowns across 16 games. To wrap up his professional injury history, Niklas injured his left wrist in Week 3 last season, and a season-ending procedure was promptly ordered up. As he goes through his third full offseason program, he has already been termed one of the Cardinals' starting tight ends (also, Jermaine Gresham) by head coach Bruce Arians, per Kyle Odegard of the team's official site. Whether the role allows Niklas to tap into his potential remains to be seen, but Gresham is the proven commodity among the tight ends, who most perform ably as both pass catchers and blockers in Arians' offense. As a result, Niklas will be hard-pressed to produce consistently as the fifth or sixth option, at best, within the passing attack.
Heath went down in the Texans' divisional-round loss to the Patriots last January. While it still isn't certain what specific type of knee injury he was dealing with, the second-year Michigan State product did not require surgery and has been participating in the outset of OTAs.
Fowler missed his entire rookie season due to a torn ACL but returned to the field in 2016, recording four sacks and 32 tackles in 16 games. He now heads into training camp completely healthy for the first time in his career with a sharpened burst and agility. All this considered, as long as he can stay healthy, Fowler could be in line for his best season yet.
Allen took a step back in his first season at Houston due to lingering injuries and a position change. However, after undergoing offseason ankle surgery, the 27-year-old is aiming for a bounce back year. "My ankle feels pretty good," Allen noted. "It was more of a cleanup thing. It was something that had been bothering me for a little while." In addition, Allen has spent the offseason changing his diet, which has helped him lose over 20 pounds. All this considered, the veteran is very optimistic for the upcoming season as he looks to bolster the Texans ground game.
Orchard finished the 2016 season on injured reserve after suffering a high-ankle sprain in Week 3. His participation in OTAs this month implies he's since received medical clearance to return to action.
Kindred broke his ankle in Week 13 last season and ultimately ended 2016 on injured reserve. His participation in OTAs suggests he's since been cleared by team doctors to return to football activities.
Oher has been under the league's concussion protocol for eight months and, despite being an active participant in offseason workouts earlier in the spring, has not been present at OTAs. However, there haven't been any signs he's legitimately considering ending his career.
Smith suffered a high-ankle sprain late in December and ultimately missed the final three games of the 2016 season. Fortunately he's been an active participant in OTAs this month and appears to be good to go moving forward.
Beachum -- who underwent surgery back in 2015 -- didn't miss a single game in 2016 but was a fixture on the injury report during the second half of the season. Considering he was recently cleared to run full speed, it shouldn't be long until he's able to join his teammates on the field.
