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.
