"I made some mistakes, I jumped offsides today, but I gave 110 percent,'' he said.
Ogunleye still added his fourth preseason sack in the first half against Bills quarterback J.P. Losman. Ogunleye was fifth in the NFL in preseason sacks heading into this weekend.
He had another big play taken away Friday night by replay. He had chased down Eric Moulds on an end-around and stripped the football but replay showed it occurred after the Bills' receiver touched the ground with his knee.
Ogunleye has had a few scrapes in preseason -- a slight groin injury for one -- but has managed to stay healthy. Last year a torn ankle tendon caused him to play most of the season in pain and led to a sub-par five-sack season. That's all in his past.
"It just feels good,'' Ogunleye said. "You can doubt yourself after the season you had last year and you're hoping you bounce back with everybody and you've got critics here and there but the way I'm playing now, I'm just excited to contribute.
"But I think it's a sigh of relief for me to know I'm back from this injury. It's a sigh of relief for the Bears community and the Chicago community to know that this is the kind of guy that they traded for and this is the type of play that they're going to see for 16 games."

Head coach Lovie Smith said that he needed to review the film against the Buffalo Bills before making a decision to change quarterbacks.
Chad Hutchinson finished with a 0.0 passer rating after throwing two interceptions and connecting on just 3-of-14 attempts for 33 yards.
At this point, Smith is unsure of who will be under center when the season starts.
"I can say that for a couple other positions too," he said. "I would just say, you saw Chad's effort, we're not pleased with that. And I really think that Kyle did a great job when he was in there."
The Bears have just three practices before the preseason finale. If a switch is going to be made it likely be announced today.
For the first time in four preseason games, Mark Bradley failed to lead the Bears in receiving yardage. While getting a chance to work with the first string offense, the rookie was shutout. He caught two passes for 27 yards in the fourth quarter, including a 17-yard reception on the game-winning drive.
