"I don't know if he's close. It's probably going to be a few more weeks," Bears general manager Jerry Angelo said on Monday. "He didn't break anything, that's the good news. But it's an injury that every player's body handles differently. So we're going to have to be patient and wait and see."
Bennett worked out with the Bears training staff prior to Monday night's 24-13 loss against the Detroit Lions at Ford Field. He was also observed running sprints on the side during the team's practice last week at Halas Hall.
"It's killing me, man, not being on the field," Bennett said. "But at the same time, I can't rush it. I just have to listen to the doctors and be ready when they tell me I can come back."
Bennett hasn't seen the field since the first half of the Bears' Week 2 loss to the Saints, when New Orleans safety Roman Harper lowered his head and hit Bennett square in the chest on a slant route. Bennett actually returned to action for a brief time, but was later ruled out to start the second half.
The loss of Bennett has hurt the offense; the dependable and tough receiver is known to be a favorite target of Bears quarterback Jay Cutler.
In other injury news, the Bears listed defensive end Corey Wootton (hand) as probable on the official injury report, but he was inactive Monday night at Ford Field. Wootton broke his left hand in practice last Thursday, and may be forced to miss the Bears game against the Minnesota Vikings on Sunday.
The Bears also went with just two running backs against the Lions, as third stringer Kahlil Bell was inactive.
For the Lions, rookie defensive tackle Nick Fairley was activated for the game after missing the season's first four games because of a left foot injury.
Fairley, a first-round draft pick from Auburn, had surgery on his foot early in training camp. He was at practice last week, but coach Jim Schwartz was noncommittal about whether he would be able to contribute against the Bears.
Detroit linebacker Justin Durant, who is recovering from a concussion, was deactivated after experiencing more symptoms shortly before the game.
