Penn 25, Bucknell 24
PHILADELPHIA--Dan Curtin sacked Bucknell quarterback Scott Auchenbach for a safety with 5:58 left to lift Penn (4-1, 2-0).
A 46-yd. field goal attempt by Bucknell's Steve Barimo with 20 seconds left in the game hit the crossbar.
Bucknell had taken its first lead, 24-23, in the fourth period on Brian Henessey's 3-yd. touchdown run.
But the safety--Penn's only score of the second half--put the Quakers ahead to stay.
