Maryland defensive end David Mackall has been suspended indefinitely for a violation of team rules, coach Randy Edsall said.
Maryland did not specify what the violation was.
Mackall -- backed up by sophomore Marcus Whitfield -- has played in all eight games this season and has three sacks.
He joins a list of other Terps suspended at various points -- and for various durations -- this season.
The list includes: fullback Rahsaan Moore, defensive end Cody Blue, receiver Ronnie Tyler, receiver Quintin McCree and running back D.J. Adams.
