ALLEN PARK — Several Lions have bumps and bruises, but they were all on the practice field today (Friday).

Safety Louis Delmas (knee) was the only exception and he usually doesn’t practice on Friday. He uses it as a rest day.

It’s possible several of the players practiced on a limited basis.

Of course Nate Burleson, who had surgery on his broken arm on Wednesday, was absent.

It’s expected Burleson will be replaced by committee on Sunday. Expect Reggie Bush and Ryan Broyles to line up more often in the slot. 

The Lions (2-1) play the Chicago Bears (3-0) on Sunday at Ford Field. Kickoff is 1 p.m.
