Taylor Swift watched on at the Arrowhead Stadium as boyfriend Travis Kelce and the Kansas City Chiefs failed to clinch the AFC West title after a shock 20-14 Christmas Day defeat to the Las Vegas Raiders.

Chiefs were bidding to put the seal on an eighth successive AFC West crown but a pair of touchdowns in the second quarter from Bilal Nichols and Jack Jones gave the Raiders a lead that the hosts could not overturn.

Justin Watson’s fourth-quarter touchdown gave the Chiefs hope but Raiders’ defence triumphed as they sealed back-to-back wins to move up to second in the division.

The Philadelphia Eagles reignited their push for the NFL East title as they beat the New York Giants 33-25, ending a three-match losing run.

Jalen Hurts threw for one touchdown and broke the NFL record for most rushing scores in a season by a quarterback as he went over from a yard for his 15th of the season.

The win lifts the Eagle to 11-4 with a one-game lead over the Dallas Cowboys, needing to win their remaining games to ensure the divisional crown.
