Nebraska junior defensive end Randy Gregory is doubtful for Saturday's game against FCS opponent McNeese State because of a left knee injury.
Gregory (6-foot-6, 248 pounds) was injured on the Huskers' first defensive series of the game this past Saturday against Florida Atlantic; afterward, coach Bo Pelini said Gregory "probably could've went back in the game."
But Pelini told reporters Monday morning that Gregory -- who led the Big Ten in sacks last season -- is doubtful for this week and "probable" for Fresno State on Sept. 13.
It wouldn't be that big a surprise if Gregory is held out until Sept. 20 against Miami. He is Nebraska's best defensive player, and there would seem to be no reason to play Gregory in two games Nebraska should win without him.
NFL Media draft analyst Bucky Brooks wrote last month that Gregory was "already generating buzz" as a potential first-round pick.
Junior walk-on Jack Gangwish (6-2, 260) came in for Gregory against FAU and seems likely to get the start if Gregory can't play against McNeese State.
After the win over FAU, Gangwish was asked if Gregory offered him any advice.
"Those are some pretty expensive legs," Gangwish told the Omaha World-Herald. "I think they were more concerned about what was going on with him than having him interact with us."
