Dwayne Harris sped 100 yards with a kickoff return against his former Dallas teammates seconds after the Cowboys had tied Sunday's game, and the New York Giants moved atop the NFC East with a 27-20 victory.
Harris spent four seasons in Dallas without running back a kickoff for a score. But he tied a Giants record set in 1994 by romping untouched to the end zone.
New York (4-3) snapped a five-game slide against Dallas (2-4) thanks to big plays by its defense and special teams. Dominique Rodgers-Cromartie had two interceptions, returning one 58 yards for a touchdown.
