John Shurna questionable vs. OSU

EVANSTON, Ill. -- Northwestern forward John Shurna was still showing concussion symptoms Friday. He will be a game-time decision for Saturday's contest against top-ranked Ohio State.

Shurna, the Wildcats' leading scorer, suffered a concussion when he collided with a basket post during the first half of Wednesday's loss at Minnesota. He played following the collision, and the concussion was discovered after the game.

Shurna sat out practice on Thursday and Friday.

"He saw the doctors today and said he has improved, but it'll probably be decided [Saturday] morning," Northwestern coach Bill Carmody said Friday. "I really don't know. I'm hoping."

Shurna's concussion adds to what has already been a trying season for the Wildcats junior. He had been battling a high ankle sprain since Dec. 23. His performance and numbers had dropped the past month after putting up 20-plus points per game during the nonconference season.

Shurna also cut his chin during the collision on Wednesday and had to have it bandaged.

"I don't think he's in great spirits," Carmody said. "I'm not dealing with the personality right now. It's just whether he can play. If he can't, I'll talk to him. If he can, I'll talk to him. For now, I let the doctors do what they do."

Shurna is averaging a team-best 19 points per game. He also is averaging 4.7 rebounds, 1.4 steals and shooting 52.2 percent on 3-pointers.

Northwestern has lost all six of its meetings with ranked teams this season. The Wildcats have also never defeated the nation's No. 1-ranked team in the history of their program.
