DURHAM, N.C. (AP) — The 21st-ranked Duke Blue Devils will have their Hall of Fame coach on the sideline this weekend.

Mike Krzyzewski has announced on his weekly radio show that will be back for Saturday's game against Pittsburgh. Krzyzewski took a leave of absence four weeks ago to undergo back surgery, his fifth medical procedure since the end of last season. He revealed on his SiriusXM broadcast Wednesday that he's watched parts of Duke's workouts for the past week and a half.

The Blue Devils were ranked eighth in the AP poll when he announced that Jeff Capel would serve as interim coach. They won just four of seven games under Capel and have fallen to 21st in the poll, but they come off road wins at Wake Forest and No. 20 Notre Dame.

Krzyzewski turns 70 on Feb. 13.
