Boston College running back Montel Harris, the Atlantic Coast Conference preseason player of the year, will miss the next three to four weeks of practice with a knee injury.

That would keep him out of BC's opener against Northwestern on Sept. 3 and perhaps Game 2 the following week against Central Florida.

Harris needs 126 yards to become the Eagles' all-time leading rusher. With 1,002 yards, he would set the conference record for rushing, as well.

He missed last year's Fight Hunger Bowl with the knee injury and had a relapse during practice this week.
