Cowboys defensive end Jermey Mincey was diagnosed with a concussion late this week, putting him out of Sunday’s game.
Mincey, the starting right end, did not appear on the practice report Wednesday as he practiced fully. The Cowboys listed him as limited Thursday with an illness. On Friday, the team called it a concussion.
His absence puts the Cowboys down three right ends. Greg Hardy has another two games to sit out in his four-game suspension, and Randy Gregory continues to rehab the ankle he injured in the season opener.
Jack Crawford likely will start at right end. He played mostly inside for his 28 snaps in the season opener, but with Gregory out against the Eagles, Crawford played only one snap inside and the other 36 at end.
The Cowboys have only three healthy defensive ends in Crawford, DeMarcus Lawrence and Ryan Russell. They also have linebacker Kyle Wilber, a former defensive end whom they can use as a pass-rusher.
The Cowboys had only three defensive ends on their 46-man roster last week, with Lawrence playing 51 of 62 snaps.
Wilber (hamstring) and Russell (groin) are probable. Russell, a fifth-round pick, was inactive for the first two games.
Tight end James Hanna (knee) also is probable.
Left guard Ron Leary (groin) is questionable after being limited in practice again Friday. Rookie La’el Collins will start if Leary can’t play.
