Kevin Kolb returns to practice

Buffalo Bills quarterback Kevin Kolb, who dressed but did not play in Sunday's preseason opening win over the Indianapolis Colts, practiced on Monday but was still limited by a lingering knee injury.

"He's just coming back so we're working him into it," head coach Doug Marrone said Monday. "I think it will just get better and better as we go through because really, he hasn't practiced in quite a time."

Kolb practiced last Friday, but had missed most of last week after leaving training camp for a death in the family.

"I think we're just taking it slowly and carefully," Kolb said Monday. "I'm trying to push the envelope. I'm trying to get out there and be a little part of this fun."

Early in camp, Kolb received the bulk of first-team reps at quarterback, but he slipped on a wet rubber mat while running between practice fields on Aug. 4, injuring his knee.

"I was coming off my best practice probably and feeling really comfortable," he said. "For something goofy like that to happen was very frustrating."

Kolb said he suffered " a little knee cap damage" on the slip-and-fall.

During Kolb's absence, rookie EJ Manuel took the helm in practice and started in Sunday's win over the Colts. The Buffalo News reported that Kolb was the third quarterback in Monday's practice.

"When they said they were going to ease me in, I said, 'No, you're not. I want you to put me in.' That's the way I feel," Kolb said. "They're going to play it smart and they can see my progress probably better than I can. Hopefully I can take the pride out of the deal and let my injury just come along."

The Bills will host the Minnesota Vikings for their second preseason game Friday, and Marrone said "it's too early" to know if Kolb will play.
