The Cowboys defensive leader and one of the NFL’s best sack artists is playing with a bum wing. Defensive end Demarcus Lawrence revealed on Friday that he is currently playing with a torn labrum in his shoulder, and has had it dating back to last season.

“This is the first time it popped out on me last week,” Lawrence told the Dallas Morning News. “I was about to cry on the sidelines if y’all didn’t notice. It was hurting bad. It feels better now.

“It’s been torn two years ago and you never knew it, right? I’ll work through it like any other injury.”

Lawrence has been practicing with a shoulder harness and will likely play against Jacksonville with the protective gear to keep his shoulder from popping out again.

Lawrence has suffered through injuries pretty much since he’s been in the league, and this fact is likely part of the reason Dallas hesitated to seriously work on a long-term deal this past offseason, instead choosing to place the franchise tag on him despite being second in the league with 14.5 sacks.

As a rookie, Lawrence broke his foot early in training camp, setting him back in his early indoctrination to the league and leaving him unable to make much of an impact on the 2014 season. He dealt with a back injury in 2015 that caused him to have surgery following the year, and then needed a second back surgery following 2016 as he played with an issue not cleared up the prior offseason. Now he reveals he played 2017 injured (remarkable considering his performance) and is still suffering this year.

Lawrence is currently third in the league in sacks with 5.5 sacks, just a half sack behind Houston’s J.J. Watt and Pittsburgh’s T.J. Watt.
