Former Iowa State head football coach Earle Bruce is fighting the early stages of Alzheimer’s disease, according to the Columbus Dispatch.

“We’ve known for a while,” Bruce’s daughter, Lynn, told the Columbus Dispatch, “but we’re seeing a change, a little bit more progression. He’s starting to not remember certain dates and things like that.”

Bruce, 86, had a stroke two years ago and has reportedly dealt with impaired speech since then.

Bruce coached at Iowa State from 1973-78. After going 12-21 during his first three years in Ames, Bruce turned the program around and won eight games each of his final three years for a 24-11 record.

He was a two-time Big Eight Conference Coach of the Year (1976-77) and his .529 winning percentage at Iowa State is the best in school history among all coaches who coached 50 or more games.

After his time at Iowa State, Bruce was the head coach at Ohio State University from 1979-87, where he won the Big Ten Conference four times. He also coached Northern Iowa for one season in 1988. Bruce was inducted into the College Football Hall of Fame in 2002 for his accolades as a head coach.
