Nebraska's defensive line situation is tenuous at best. And now we learn that one of the group's potential contributors is dealing with a legal issue.

The Omaha World-Herald's Sam McKewon reports that redshirt freshman defensive end Avery Moss appeared in court on Friday and faces a July 23 trial date on indecency and disturbing the peace charges. Moss stands accused of exposing himself to a female employee at a Nebraska residence hall convenience store twice in a matter of hours on Dec. 15, according to a police complaint.

Moss has pleaded not guilty to the charges, which include public indecency -- a misdemeanor that carries a maximum of six months in jail -- disturbing the peace and failing to appear for a scheduled Jan. 22 court date.

The World-Herald reports that Nebraska head coach Bo Pelini has been aware of Moss' situation. Both Moss and his lawyer declined to comment to the paper on Friday.

The 6-foot-2, 270-pound Moss played in three games and registered four tackles last season before a shoulder injury led to a medical redshirt. This spring, defensive coordinator John Papuchis told ESPN.com that Moss and fellow redshirt freshman Greg McMullen had "taken a significant amount of first-string reps" on the defensive line.

The defensive line is probably the biggest question mark for Nebraska this season and the key to whether the Huskers can compete for a Big Ten title. Junior-college import Randy Gregory is expected to help right away at defensive end, along with senior Jason Ankrah and McMullen.
