There was no sign of Bill Belton at practice on Wednesday in the first 15 minutes that reporters were allowed to watch.
Belton, the Nittany Lions' No. 1 running back in the season-opener against Ohio, missed the past two games because of an ankle injury. He is listed as day-to-day.
Meanwhile No. 2 running back, Derek Day, was in full pads. Day missed last week's game against Navy and was also listed as day-to-day for Saturday's game against Temple.
"I would say that Day is a little bit ahead of Belton," coach Bill O'Brien said at Tuesday's press conference. "But they are both day-to-day, and we are going to continue to monitor that."
