Penn State starting right tackle Lou Eliades suffered a serious knee injury in Saturday's win against Temple and could be sidelined for an extended period.
Coach Joe Paterno said after the game that he's "almost sure [Eliades has] a torn ACL," adding that the senior likely will miss the remainder of the season.
The 6-foot-4, 310-pound Eliades started at right guard last season before being moved to tackle.
Penn State opens the Big Ten season next week at No. 18 Iowa.
