(AP Photo/Ohio State University, Jay LaPrete) (Newser) – Police in Columbus, Ohio, are searching for an Ohio State University football player who disappeared on Wednesday after an ominous text to his mom. “I am sorry if I am an embarrassment but these concussions have my head all f---ed up," wrote Kosta Karageorge, according to the Columbus Dispatch. The 22-year-old senior was last seen leaving his apartment about 2am Wednesday, apparently upset, and he failed to show up at football practice the next day. His family says he has a history of concussions and sometimes gets disoriented, reports Cleveland.com. “We’re very concerned that he’s not himself and that he maybe doesn’t know what’s going on,” his sister says in a previous Dispatch story. Karageorge is a 6-foot-5, 285-pound defensive lineman who joined the football team only this year as a walk-on. He had previously wrestled for OSU for three years. "While we are not able to discuss or comment about the medical care regarding our student-athletes, we are confident in our medical procedures and policies to return athletes to participation following injury or illness," says the football team's doctor in a statement. Former players are raising money for a reward. Karageorge was supposed to be on the field today to be recognized with the team's other seniors.
