LINCOLN, Neb. (AP) _ Nebraska defensive end Randy Gregory is doubtful for this week's game against McNeese State because of an injury to his left knee.

Gregory left the Florida Atlantic game after the Cornhuskers' first defensive series Saturday. Coach Bo Pelini said Monday that Gregory had an old basketball injury ``flare up,'' and it caused a clicking sensation in his knee. Gregory, who led the Big Ten in sacks last season, underwent a procedure Sunday to remove scar tissue.
Pelini said Gregory should return for the Sept. 13 game at Fresno State.

The coach said Gregory probably could play against McNeese State, if needed, but that he wanted to give him plenty of time to recover.

Junior Jack Gangwish will make his first career start against McNeese State.
