The Kansas City Chiefs’ play-off hopes are hanging by a thread after losing 31-28 at the Dallas Cowboys on Thanksgiving.

The Cowboys have traditionally hosted games on the American holiday since 1966 and ‘America’s Team’ produced a superb performance to overcome the Chiefs despite Patrick Mahomes throwing four touchdown passes as he returned to his native Texas.

Mahomes has led the Chiefs to five of the past six Super Bowls, winning three, but they now have a 6-6 record and are in danger of missing out on the play-offs for the first time since the 2014 season.

The Cowboys came from behind to lead 17-14 at half-time, but a tense finish began with the Chiefs taking a 21-20 lead at the start of the fourth quarter.

Quarterback Dak Prescott then held his nerve as Dallas scored 11 points on their next two possessions to keep them clear, despite a late Chiefs reply.

The Cowboys have now claimed back-to-back wins over both of last season’s Super Bowl teams in just five days after beating the Philadelphia Eagles on Sunday.

After a stirring 21-point comeback against the Eagles – who denied the Chiefs a three-peat in February – the win over Kansas City is a third in a row for Dallas, to improve to 6-5-1 and keep alive their own hopes of sneaking into the post-season.

With five games left, Dallas are second to the Eagles (8-3) in the NFC East while the Chiefs trail both the Denver Broncos (9-2) and Los Angeles Chargers (7-4) in the AFC West.
