RALEIGH, N.C. (AP) - Dave Doeren is leaving Northern Illinois to take over at North Carolina State.

N.C. State announced Doeren's hiring Saturday - less than 24 hours after he guided the 19th-ranked Huskies to their second consecutive Mid-American Conference championship, and just six days after the Wolfpack fired Tom O'Brien.

Doeren claimed a MAC title both years he has been a head coach and is 23-4 since taking over the Huskies before the 2011 season with a 17-1 record in conference play.

N.C. State athletic director Debbie Yow calls Doeren ``a highly motivated overachiever.''

Doeren - who turns 41 on Monday - replaces O'Brien, who was fired following six inconsistent seasons and no Atlantic Coast Conference title-game appearances with the Wolfpack.
