Daryn Colledge rarely misses practice and he never misses games but the Green Bay Packers have concern that the veteran left guard will not be able to go Sunday night against the Dallas Cowboys at Lambeau Field.

Colledge has his back seize up on him in practice on Wednesday, according to the Green Bay Press-Gazette, and didn’t practice Thursday. His status for the game remains up in the air, and that puts his consecutive games streak of 72 in jeopardy.

“Daryn doesn’t miss practice very often, and he doesn’t miss games,” Packers coach Mike McCarthy said, according to the report. “We’ll have to see where he is and see if he can go at practice tomorrow. I don’t have all the information. There was some testing done while we were at practice, so I’ll know.”

Jason Spitz is in place to back Colledge up and it’s possible he will be starting.
