Heavy snow covered the field and stands for the Big East game on Saturday afternoon. When Pitt's Dion Lewis scored the second of his three touchdowns in the half, students pelted him with snowballs and were told to stop.
A school spokesman says the mascot also was told to stop throwing snowballs in the stands and pushed a security guard, knocking both of them to the ground. The mascot was detained and cited. He was not identified.
A backup mascot took his place at halftime.
