Surgery in the morning— $hon (@_ShonL2) August 26, 2014
Ohio State freshman cornerback Marshon Lattimore is set for surgery Wednesday for a lower leg injury, sources told Eleven Warriors Tuesday night.
Lattimore was expected to compete with Eli Apple and Gareon Conley for playing time at cornerback. He missed time early in the team's training camp with a minor injury.
Lattimore came to Columbus as one of the nation's top recruits out of Glenville High School in Cleveland.
Ohio State did not immediately respond to request for comment.
