There were several key injuries across the league's training camps reported during Thursday's practices.
Mike Wallace, the highly paid and highly talented Miami Dolphins receiver, missed his second straight day of practice with "a tweaked hamstring."
Chiefs safety was carted off the field and treated for a lower leg and/or right foot injury. Head Coach Andy Reid determined it to be "ankle soreness," noting that it definitely wasn't anything regarding the Achilles.
Continuing with the trend of starting safeties, Green Bay's Morgan Burnett sat out with an ankle injury. Head coach Mike McCarthy didn't provide a timetable for his return, but did say the injury "gives someone else an opportunity." First-round pick Ha Ha Clinton-Dix is the big beneficiary here.
Calvin Pryor returned to Jets practice following a concussion.Pryor sustained the concussion Saturday and entered the NFL’s post-concussion protocol, for which he has to pass a series of cognitive tests and be cleared by an independent neurologist before he is allowed to fully return to practice.
The Colts offensive line took a hit when offensive lineman Donald Thomas suffered a torn quad. He'll miss the entire 2014 season after missing the 2013 season with that same injury.
One last significant injury occurred when Baltimore Ravens fourth round draft pick, Brent Urban, tore his ACL, just after making a comeback off of an ankle injury.
