Bears' Austin Booker: Won't return Sunday

Booker (knee) has been ruled out ahead of Sunday's matchup against the Ravens, Chris Emma of 670TheScore.com reports.

The second-year pro from Kansas practiced in full throughout the week, but it now appears he's not ready to return from IR just yet. Booker has yet to play this year after recording 21 total tackles, including 1.5 sacks, across 17 games during his rookie season.
