A longtime Michigan State strength coach has decided to call it a career while the program is going through some changes.

On Thursday, Ken Mannie announced via a Twitter post that he will be stepping down from his position as the strength coach of the Michigan State football team. He was in the position for 25 years.

“Spent the past several months informing family and close friends,” Mannie wrote. “Wanted to wait till things settled a bit on the current situation to make this public. So much gratitude to express over the ensuing months…but here’s a start. And players…let’s finish this week off strong!”

Mannie’s announcement comes a day after Mel Tucker was named the head coach at Michigan State, replacing Mark Dantonio after 13 seasons. He had spent a total of 45 seasons in the field at the college or high school level.

In 2014, Mannie was inducted into the USA Strength/Conditioning Coaches Hall of Fame’s collegiate division. In 2015, he was named the Strength and Conditioning Coach of the Year by FootballScoop.

This will be another position Tucker needs to fill as he assembles his staff in East Lansing.
