The Cowboys fumbled once but recovered it.The Cowboys’ party started after the Giants advanced to the Dallas 8-yard line on their opening drive.After a false-start penalty and a low snap cost the Giants 19 yards, Graham Gano’s field goal was blocked. Juanyeh Thomas bounded through untouched to make the block, and Noah Igbinoghene returned it 58 yards to pay dirt.
