ALLEN PARK -- Stephen Peterman had no reason to think his knee injury was serious, but there was a question. On Tuesday the Lions dodged a bullet when an MRI showed no damage to Peterman’s knee.

“I got kicked the other day pretty hard in practice, it kind of swelled up on me and they wanted to do some checks and make sure everything was OK and everything’s fine. We’ve been working to get the swelling out,’’ said Peterman who starts at right guard.

Despite the swelling he practiced at Ford Field on Saturday and went through the first practice on Sunday.

Coach Jim Schwartz said he didn’t lose any sleep because he didn’t think it was a serious injury.

He learned last season what it was like to play without Peterman in the lineup when he went out with an ankle with seven games left.

“Any time on the offense line you want to have continuity. We didn’t have enough of it last year. Petey played well early in the season for us, after he got hurt it was hard to replace him especially with what was going on at left guard,’’ said Schwartz referring to the revolving door at left guard.

Peterman watched practice on Tuesday and expects to be back in action shortly.
