CHICAGO -- Chicago Bears cornerback Zack Bowman is scheduled to undergo an MRI early this week to determine the severity of a foot injury suffered late in the third quarter of a 23-20 loss to the Seattle Seahawks on Sunday, according to an NFL source.

Bowman appeared to hurt his foot while pushing Seattle wide receiver Deon Butler out of bounds after a 15-yard completion.

After starting 12 games last season, Bowman has been coming off the bench and rotating with Tim Jennings, who also re-injured a finger Sunday, at left cornerback the past three weeks.

"That's what I'm here for, just to help the team as much as I can," Jennings said after Sunday's game. "I've started the last three weeks, and me and Zack have been rotating. He's a great addition [to the defense], I'm a great addition, but now I think I'm going to get the bulk of the load. I just hope Zack can come back as fast and healthy as possible, but [it's] next man up. We just got to keep it going."

Meanwhile, safety Danieal Manning was forced to the sidelines late Sunday with a rib injury. Manning initially hurt his ribs while combining with Charles Tillman to make a tackle in the first half, but the safety played through the pain.

However, Manning felt his ribs tighten up after returning a fourth-quarter kickoff 89 yards for a touchdown that was taken off the board because of a holding penalty.

Manning tried to continue to play, but the pain proved too great, and veteran Josh Bullocks took over at one of the safety spots.
