Police and family members are looking for a senior defensive lineman on the Ohio State University (OSU) football team after he went missing early Wednesday morning.

According to the Columbus Dispatch, Kosta Karageorge's sister Sophia said her brother was last seen at his E. 7th Avenue apartment at 2 a.m. Wednesday. His roommates reportedly told the family that Karageorge went out for a walk and did not return.

OSU has not commented publicly on the matter, but anyone with information that could lead to Kosta Karageorge's whereabouts is encouraged to call 614-747-1729.

"He had some extenuating circumstances that night that lead us to believe he was upset," Sophia told the Dispatch. "He did not take his motorcycle, and he does not have his car on campus.

"So he was either picked up, went on foot or took public transportation. He does not have his wallet or any identification on him that we know of because his girlfriend has his wallet."

Also a former OSU wrestler, the Buckeyes' defensive tackle is six-feet-five and weighs 285 pounds. His sister said he was wearing a black pair of sweatpants over his jeans, a black hooded sweatshirt, a black beanie and black Timberland boots.

Police were able to track the location of his cell phone via GPS, the Dispatch reported, but did not find him or the device. Sophia said her brother missed Wednesday's practice and an event called Senior Tackle, an OSU tradition. As a senior, Karageorge was set to be honored alongside 23 teammates Saturday for the Buckeyes' final home game of the regular season.

"He never misses practice," she said. "I've seen him go to wrestling practice with a broken foot. I've seen him sick as a dog go to practice. He's always on schedule. He always has somewhere where he checks in."

As an athlete in two contact sports, Karageorge has certainly suffered more than one concussion. Even though he would listen to OSU's doctors and follow their instructions, the family is concerned about his mental state.

"We're very concerned that he's not himself and that he maybe doesn't know what's going on," Sophia Karageorge told the Dispatch. "Every time he's had a concussion, he's been evaluated and listened to his trainers. He's been properly taken care of by OSU the entire time he's been an athlete for them.

"But... his repercussions from them have been long-term or delayed later after the fact."
