COLUMBUS, Ohio (AP) — The sister of an Ohio State football player says his family has reported him missing after he left his apartment, then uncharacteristically missed two practices and didn’t check in.

She tells The Columbus Dispatch 22-year-old Kosta Karageorge was last seen at his apartment around 2 a.m. Wednesday.

Sophia Karageorge says her brother apparently was upset, and roommates said he went for a walk, dressed in all black.

Police were looking for the 6-foot-5 senior defensive tackle, but weren’t available for comment Thursday.

His sister says he didn’t take his wallet or motorcycle. She says he has a history of sports-related concussions, including one a month ago, and his family was concerned that he might have become disoriented.

The former wrestler joined the football team as a walk-on this season.

There was no immediate comment by Ohio State on Karageorge.
