Bears SLB Pisa Tinoisamoa will not play Sunday vs. the Lions.
Nagging soreness in his right knee kept him out of practice Wednesday and limited him on Thursday, and reports indicate he was not on the field for practice on Friday. The same issue kept Tinoisamoa out against the Dolphins in Week 11.
SLB Nick Roach, who started 15 games in 2009, will get his second start of this season against Detroit. Roach has made six tackles in the 10 games he's played in.
