Bill Carmody was still waiting for the final word from the medical staff, but the Northwestern coach said he doesn't expect forward Jared Swopshire (knee) or center Alex Olah (concussion) to be available when the Wildcats travel to Ohio State on Thursday night.

Both players were injured in Sunday's loss at Iowa. Olah sustained a blow to the head and was taken to the locker room immediately, where a baseline test confirmed he had suffered a concussion, according to Carmody.

Swopshire injured his knee while attempting a layup a few minutes later.

"Some times guys are experienced and are average but he has really started to influence games the last  few weeks and be more aggressive," the Northwestern coach said of Swopshire. "He has been our leading rebounder and a real presence out there.

Swopshire was averaging 9.7 points and 6.7 rebounds per game for the 'Cats. He will be replaced by freshman Kale Abrahamson. James Montgomery III will also likely see increased minutes.

"Kale can make some shots," Carmody said. "Now he's going to have to rebound more because Swopshire isn't out there and Alex isn't out there."

Mike Turner has been logging most of the minutes as the backup center but is only 6-foot-8. Junior forward Nikola Cerina has been slow to recover from an ankle injury but the 6-9 junior will need to step into a much larger role with Olah sidelined.

"The problem with Mike is he's undersized and he has been in foul trouble," Carmody said. "He has this tendency to foul guys a lot and that's a little scary."
