ANN ARBOR, Mich. (AP) — Michigan has fired football coach Brady Hoke after four seasons.

Interim athletic director Jim Hackett made the announcement Tuesday after weeks of speculation about Hoke’s future.

The Wolverines have struggled to regain their status among the top programs in the Big Ten, much less college football.

Hoke was an assistant at Michigan before turning around San Diego State and Ball State as a head coach. After he replaced Rich Rodriguez, the Wolverines won the Sugar Bowl and finished the 2011 season 11-2.

Hoke’s recruits were well regarded, but the results on the field didn’t measure up. Michigan went 8-5 in 2012 and 7-6 in 2013. This season, they were 5-7. Hoke was 31-20 overall at Michigan.

“I wanted to make sure that Brady received adequate time to exhibit the results that would come from his effort and I believe that Brady and our coaching staff had enough time to produce those results and unfortunately they are not there,” said Hackett, who took over as AD last month. “In the end, I feel that moving in a different direction is the right decision.”
