Harrison knows time could be running out

LAKE FOREST, Ill. -- Marcus Harrison understands his time in Chicago could be coming to an end. As final cuts loom at the end of the week, the Bears' 2008 third-round draft pick might get caught up in the numbers game at defensive tackle, a position the club recently addressed in free agency and in the draft.

"If it happens, it happens," Harrison said Tuesday. "We have a lot of good guys here, so I can't do nothing but practice hard every day and make it tough on the coaches. If they decide to go with me, they do. If they don't, they don't. I just can't do anything but practice hard every day, and that's what I'm doing."

Complicating Harrison's situation is the fact he reported to training camp overweight, which kept him off the practice field the first week of camp. The defensive tackle only dressed for five games in 2010, after starting a career-high nine games in 2009. Harrison recorded a career-high two sacks and two tackles for a loss in his rookie campaign.

Harrison's final chance to make an impression of the coaching staff likely is Thursday night in the Bears' preseason finale against the Cleveland Browns.

"For me, I just feel like I need to be consistent," Harrison said. "I think that's what [defensive coordinator] Rod [Marinelli] wants to see out of me, as far as small things like technique and foot work. Just going out there trying to be dominant and making plays. I'm just pretty much trying to go out there and put it on film because that's what tells the truth here."
