But Fordham stormed back with an 8-yard TD from Nebrich to Dan Light. On the next possession, Chase Edmonds (26 carries, 142 yards) put the Rams at the 4 with a 33-yard gainer. On the next play, Nebrich faked the handoff and ran it in.
Nebrich added two more TD passes in the fourth quarter, a 5-yarder to Marcus Jones and a 25-yarder to Brian Wetzel.
