Lincoln -- With cold and blustery conditions outside, the Nebraska football team worked out Wednesday afternoon in the Cook Pavilion for nearly two hours in preparation for Saturday’s 2:30 p.m. game at Kansas.

Earlier Wednesday, sophomore safety Josh Bullocks was named one of 12 semifinalists for the 2003 Jim Thorpe Award, given annually to the nation’s top defensive back. Bullocks is one of three Big 12 players to make the list, and the only sophomore.

"He’s certainly deserving of it, he’s had a great season so far," head coach Frank Solich said. "We keep plugging him into more things. We’re lining him up, and he’s also catching punts, as of now. We’ll keep working with him, and he may see some action on that end of it."

Solich also said that the injury bug has bitten the Huskers.

"Greg Austin will be out for the rest of the season," Solich said. "He sustained an injury yesterday that will require surgery. That’s tough on him and on the team because he was really coming at the offensive guard spot and getting some playing time. We’ll continue to alternate in Brandon Koch at the guard spot with Jake Anderson and Mike Erickson."

Austin, who was listed second on the depth chart at the right guard spot, had seen action in four games this season including the last three.

In addition to Austin’s injury, the team learned that senior offensive tackle Tim Green’s career will prematurely end due to chronic back problems.

"Tim Green has not been able to practice for a number of weeks," Solich said. "He will not be able to finish out the season."

The Huskers will return to the practice field on Thursday afternoon.
