On Wednesday, the following text was added to the site's BUZZ section:
While discussing the previous play with another player, Coach Paterno was overrun by a tight end and safety at full speed at Tuesday's practice. Nothing was broken and he finished practice, but as expected, awoke sore today and will limit himself to team only activities for the next few days.
Paterno, who became head coach of the Nittany Lions in 1966, turns 80 in December.
Penn State faces Northwestern at Beaver Stadium this weekend. Paterno has never missed a game due to illness or injury.
