He was invisible for most of the first half of the season, but the three-time Pro Bowl defensive tackle seems to have regained his all-star form. Harris had two sacks Sunday, matching his total from the first 10 games and giving him four in the past five games.

Harris' rejuvenation started shortly after he was suspended for the Oct. 5 game at Detroit because of repeated tardiness, and his teammates have noticed the improvement in his game. Harris still is limited at practice during the week by lingering knee problems, but he's been making a difference on Sundays.

"(Opponents) have to start looking at him. They have to make sure they block this guy," defensive end Alex Brown said. "He's one of the best, if not the best, three technique (tackles) in the league, and when he's healthy and when he's playing at his top level, there's nobody better. (Even) when he's playing at 90 percent, you have to double-team him. If you single block him, he's going to beat that guy every time. When they start double-teaming him, it leaves myself, Wale (Ogunleye), Israel Idonije and Dusty Dvoracek with one-on-ones, and we've got to take advantage of it."

Brown had a sack and two quarterback hurries Sunday, and Ogunleye had two sacks and three quarterback hurries.

"Since he's gotten back from suspension, he's been a different person," Ogunleye said. "He's been very active. He's causing a lot of havoc in the backfield. We're going to do better because now the focus is going to move back to Tommie, rightfully so, and me and Alex and the guys on the edge should have a lot more fun."

--The medical news seemed optimistic Monday for safety Mike Brown and tight end Desmond Clark, although cornerback Nate Vasher's thumb injury could be more serious.

"Dez Clark has a mild knee sprain," coach Lovie Smith said. "He should be OK. "Mike Brown has a lower-leg injury. He should be all right. And Nathan Vasher has a hand injury. We're evaluating him more."

Brown walked out of the locker room Sunday without a limp, but Vasher may have aggravated the injury that caused him to miss three games in October and required surgery.

--The first lost fumble of his career didn't keep Matt Forte from a career-best 132-yard rushing day.

"It makes you mad at first," Forte said. "(Running backs) coach (Tim) Spencer came up to me and said, 'Forget about it, you've got to go back out there and play.' I just put it behind me."

On his second carry after the fumble, Forte went 47 yards for a touchdown.
