Crowell hasn't been medically cleared by Ohio State after undergoing two surgeries on his lower left leg for an injury that took place while he was in high school. O'Connor, who redshirted the 2012 season, has requested a transfer to play closer to his home in Windsor, Colo., according to a news release.
O'Connor was an ESPN 150 selection coming out of high school and rated as the nation's No. 8 guard. He initially committed to Penn State but switched to Ohio State after the child sex abuse scandal broke at PSU.
Some had wondered whether Ohio State could meet its NCAA-reduced scholarship limit of 82, as the team is set to sign a sizable recruiting class next month. Two more spots are freed up with these departures.
