Nebraska's Burkhead out with foot injury

Posted by ESPN.com's Tim Griffin

Nebraska freshman running back Rex Burkhead will be sidelined indefinitely with a foot injury that was sustained in practice on Monday.

Nebraska coach Bo Pelini told reporters Tuesday that Burkhead will be sidelined "for awhile" and offered no other specifics.

Burkhead is Nebraska's second-leading rusher with 23 carries for 118 yards and has also added eight receptions for 66 yards. He has been a key contributor on offense and special teams.

“Any time you have a football player out, you're going to miss him," Pelini said. Tuesday "I feel worse for the kid. He's a prideful, tough competitive guy."

The emergence of Burkhead helped fill the spot on Nebraska's roster where Quentin Castille played before he was kicked off the team before the season started.

The injury could be significant for the Cornhuskers as they prepare for Saturday's game against Texas Tech.

Leading rusher Roy Helu Jr. appeared to be dinged at the end of the Cornhuskers' 27-10 victory over Missouri last week, wearing a bag of ice strapped around his neck as he limped to the team bus. Helu has returned to practice with the Cornhuskers.

With Burkhead's injury, other players will be featured in Nebraska's running game. Among those mentioned by Pelini at the press conference included Austin Jones, Lester Ward, Collins Okafor, Marcus Mendoza and Dontrayevous Robinson. His special teams use could be filled by freshmen wide receivers Antonio Bell and Tim Marlowe.
