Duke's football program released its injury report on Thursday and it revealed a possible hole at the running back position as the Blue Devils face No. 22-ranked Kansas on Saturday.

Senior starting running back Re'quan Boyette is listed as probable with an ankle injury, while his backup Jay Hollingsworth is listed as questionable with an ankle injury.

DURHAM — Running back Re'quan Boyette won't play this season, Duke coach David Cutcliffe said Wednesday.

The senior had knee surgery in August and has not played in Duke's first seven games. Cutcliffe had said all along he wouldn't push Boyette to play if he wasn't 100 percent.

Re'quan Boyette, Duke's leading rusher, is out indefinitely after injuring his knee in the team's scrimmage on Saturday night. The senior running back underwent arthroscopic surgery on his left knee on Sunday, according to the team.

Duke offered no time table for Boyette's return.

Boyette led the Blue Devils with 432 rushing yards in 2007 and for the first time in his career had the starting running back job to himself. Without Boyette, Duke will lean on Clifford Harris, converted safety Tony Jackson and two true freshmen — Jay Hollingsworth and Patrick Kurunwune.

The Devils ranked last in the ACC and 117th in the country in rushing offense in 2007, averaging 64 yards per game.
