Hours earlier, Jason’s brother Travis Kelce had arrived at Arrowhead wearing his own Santa hat, while his girfriend Taylor Swift sported customized headwear that carried Kelce’s No 87 for the Chiefs’ game against the Raiders.

Monday’s meeting with the Giants is a huge game for the Eagles, whose season has hit a roadblock after three defeats on the spin.

After winning 10 of their first 11 games, the Eagles have suffered losses against the 49ers, the Cowboys and the Seahawks.

Jason Kelce will be hoping to avoid the sort of meltdown his younger brother experienced as the Chiefs struggled against the Raiders.

Cameras caught him slamming his helmet to the ground and clashing with his head coach on the sidelines.

Shortly after the Chiefs had gifted their opponents back-to-back defensive touchdowns in an NFL record seven seconds, Kelce made his way back to the sidelines and threw his helmet in disgust.

CBS cameras caught the exact moment it happened, with the helmet bouncing off the turf and into the stands at Arrowhead. A coach then tried to give Kelce a replacement, but was stopped by head coach Andy Reid, who then gave the tight end a talking to of his own.
