Husker senior running back Rex Burkhead sat out Monday’s practice as he continues to rest his ailing left knee. Burkhead did not play in Saturday’s game after missing the entire week of practice. In his postgame remarks Saturday, head coach Bo Pelini said Burkhead remained ‘day-to-day’ and expected that he would play in the next game. Junior quarterback Taylor Martinez did practice despite tweaking his left ankle in the game. He told reporters he was “beat up” but that he would be ready for this week’s contest at Michigan State.
