Bennett, who hurt himself in practice, was a limited participant Thursday and sat out Friday. Coach Marc Trestman says the Bears are "hopeful he'll play."
Bennett's absence would be a big blow for the Bears (3-5). Among NFL tight ends, he ranks second in catches (47) and fourth in yards receiving (517).
The Bears expect to have linebacker Lance Briggs back after missing three games with a rib injury. They also listed linebacker Jonathan Bostic (back), cornerback Kyle Fuller (hip, hand), safety Danny McCray (knee) and right tackle Jordan Mills (foot) as probable.
