Nebraska junior defensive end Randy Gregory, who is expected to contend for All-American honors this season, played just one series of the Huskers' rout of Florida Atlantic before leaving with an injury to his left knee.
Gregory did not return and was in street clothes on the sideline in the second half. But coach Bo Pelini told reporters afterward that Gregory "probably could've went back in the game."
There were no specifics given as to the injury.
Nebraska led 31-7 at halftime on the way to a 55-7 romp, and obviously didn't need Gregory. Still, that he was in street clothes in the second half has to be a bit concerning. On the other hand, that he was on the sideline in the second half presumably means it wasn't a serious injury.
Nebraska plays FCS foe McNeese State next week and wouldn't seem to need Gregory against the Cowboys, so even a slight injury could lead to him missing next week's contest.
Gregory had 10.5 sacks and 19 tackles for loss last season, his first with the Huskers after transferring in from junior college.
Gregory, who is 6-foot-6, has said he plans to play at almost 250 pounds this season; he was at 240 last season, and a lack of bulk was seen as a concern by Nebraska's coaches and by NFL scouts.
