Maryland has lost a fourth quarterback to a season-ending injury.
Coach Randy Edsall announced Sunday that Caleb Rowe has a torn anterior cruciate ligament and is done for the year.
The injury occurred in Saturday's 20-17 loss to Boston College. It was the first college start for the true freshman.
''I feel awful for Caleb," Edsall said.
Quarterback C.J. Brown tore an ACL in August and was replaced by Perry Hills, who tore an ACL in a game against North Carolina State on Oct. 20. Devin Burns broke his foot in that game and is also out for the year.
That means either converted linebacker Shawn Petty or converted tight end Brian McMahon will start at quarterback this Saturday against Georgia Tech.
Maryland (4-4, 2-2 ACC) has lost two straight.
