Tyler Moeller’s season could be over, according to multiple reports.

Local outlets, including recruiting website Bucknuts.com, reported that the Ohio State senior tore a muscle in his chest during the first quarter of Saturday’s 24-13 win over Illinois. Moeller jogged off the field after the play and headed to the locker room.

He did not return to the game.

When he made his way back to the sideline, Moeller, who at one point was seen crying, struggled to pull his shirt over his shoulder.

OSU spokeswoman Shelly Poe said the team did not have an official update as of Sunday evening.

Moeller missed the 2009 season when he suffered a head injury after being assaulted on vacation.

This season, Moeller saw significant playing time at the “star” position, the Buckeyes’ nickel back who acts as a hybrid linebacker and safety. Through four games, he was OSU’s second-leading tackler, behind linebacker Ross Homan. Moeller led the team with 4.5 tackles for loss.

True freshman Christian Bryant filled in for Moeller against Illinois and recorded five tackles.
