Kent State center Jason Bitsko, 21, was found dead in his off-campus apartment Wednesday morning, the team announced.
Police believe the cause of death is an undetermined medical issue.
"Kent State University and the entire Kent community mourns his passing," said Joel Nielsen, Kent State's director of athletics. "We are heartbroken by the news of Jason's death. Our thoughts and prayers go out to his family, friends, teammates and everyone whose lives he touched."
"Our players, coaches and everyone involved with our team are hurting because he was family," said Kent State head football coach Paul Haynes. "As a team, we will come together and get through this one day at a time."
Bitsko was projected to start at center this season after starting all 12 games at right tackle as a sophomore in 2013.
This would have been Bitsko's fourth year on the team.
