Maryland tailback Bruce Perry, who spent nearly half of the 2002 season injured, left yesterday's practice with a right-ankle sprain.
It is unclear how much time Perry will miss, though he needed a team trainer to help him into the training room midway through practice, a sign his participation in today's workouts is unlikely.
Perry's sprain was one in a series of injuries for the Terps yesterday. Approximately 10 players went down, including slot back Steve Suter, who pulled a hamstring.
The sprains, pulls and bruises have tempered progress in camp, with the team's first public scrimmage coming on Sunday.
"We did some good things," Maryland head coach Ralph Friedgen said of yesterday's practice, "but we keep getting hurt."
The situation is most pronounced at tailback, where Perry's sprain comes after a 2002 pulled groin muscle frustrated his efforts to surpass a 2001 performance that earned him Offensive Player of the Year honors in the Atlantic Coast Conference.
Josh Allen, Mario Merrills and J.P. Humber are also suffering from injuries.
"We're down to two tailbacks, Sam Maldonaldo and Lance Ball," Friedgen said. "But if we need to line up with these two, we will."
