"Each of our young men understands the standard we expect of them," Hoke said in a written statement. "It's one that represents this great program and university, as well as their family and teammates. When their actions don't reflect that standard, it's very disappointing, and we must hold them accountable for their decision while helping them learn a valuable life lesson."
Glasgow, who started all 13 games last season, was considered the front runner to start at center this fall. He started nine games at center and four games at guard in 2013.
Hoke would not go into the details behind the reason of suspension at his spring press conference today. He said he still hasn't made up his mind if Glasgow will be allowed to participate in the annual spring game on April 5.
"I haven't made that decision," Hoke said on Glasgow playing the spring game. "I'll think about it and work with Graham through things."
