Late in the first half of Tuesday night’s game, ISU sophomore guard Jessica Schroll collided with a Nebraska player and hit her head on the court. Schroll left the floor immediately and ISU coach Bill Fennelly confirmed postgame that Schroll suffered a concussion on the fall.

“She has a concussion, and she has a huge knot on her head,” Fennelly said. “I’m not a doctor by any means, but I would be surprised if she’d be available Saturday.”

A game-time decision is expected to be made in Colorado on Saturday.

The Midland, Mich., native is averaging 3.3 points per game in her 18.1 minutes per game this season.
