Source: Fighting Irish's Walker set to enter draft

Notre Dame junior running back Darius Walker will hold a news conference Thursday in South Bend, Ind., to announce he is entering the NFL draft, a source told ESPN's Joe Schad on Wednesday.

The source indicated Walker is likely to be the only Notre Dame junior to leave school early.

Walker's departure will hurt an Irish offense faced with rebuilding at quarterback and on the offensive line. Walker, 5-foot-10 and 208 pounds, ran for 1,267 yards and seven touchdowns this season. He had 56 catches for 391 yards and a score.
