Arrowhead Stadium fell silent after the pick-six during the Raiders' shock win.

Jones scored on a 33-yard interception return with 4:48 left in the second quarter.

He then seemed to pick out a young fan in the crowd and looked to be handing him the football.

Jones held the ball out towards the spectator in the front row.

But he then quickly pulled his arm back and held onto the ball.

CBS cameras picked up the incident during their broadcast, and fans were quick to spot what happened.

One said: "Jack Jones faked giving a kid the game ball on Christmas and then took it back. The Grinch would be proud."

Another commented: "Jack Jones doing his best Grinch impression on Christmas Day."

A third posted: "Jack Jones appeared to go full Grinch mode, pulling the ball back from a Chiefs fan."

Jones even posted an image on Instagram of him with his face as The Grinch.

But the Raiders star claimed he wasn't playing Grinch with the child.

He tweeted that another fan was about to snatch the ball, so he kept hold of it instead.

The Raiders won 20-14 in a shocker for the Chiefs which saw them fall to 9-6.

Mahomes and Co. face going on the road in the playoffs if they want to make it back to the Super Bowl.

Kansas City is the No. 3 seed in the AFC and can't catch the current No. 1 Baltimore Ravens at 12-3.
