Source: Zack Bowman's injury minor

LAKE FOREST, Ill. -- Bears cornerback Zack Bowman's right foot injury isn't believed to be serious, 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 late in the third quarter of the Bears' 23-20 loss to the Seahawks.

Further testing Monday revealed a sprain to be the extent of the injury, and the defensive back is questionable to play against Washington on Sunday at Soldier Field.

If Bowman is unable to face the Redskins, Tim Jennings is expected to handle all the work at the cornerback spot opposite Charles Tillman. Jennings has started the last three games after replacing Bowman early in the Bears' 20-17 victory over Green Bay on Sept. 27.

"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."

In other injury news, Bears coach Lovie Smith sounded optimistic on Monday that linebacker Lance Briggs could return from an ankle injury against the Washington Redskins on Sunday.
