The Colts go on to face top seed the Kansas City Chiefs.

Ezekiel Elliott scored the go-ahead touchdown as the Dallas Cowboys edged the Seattle Seahawks 24-22 in the NFC wildcard game at the AT&T Stadium.

The running back finished with 30 touches for 169 yards as Dallas' defence ended the Seahawks' streak of nine straight victories in playoff opening games.
