Injured Isiah Pacheco tries to sit on the medical table at Arrowhead after brutal hit… only for it to collapse underneath him during Chiefs-Raiders

Nothing went right for Isiah Pacheco on Christmas Day when the Chiefs running back fell through a medical table after leaving with an injury in the third quarter.

Pacheco's helmet came off after catching a pass from Patrick Mahomes with 3:22 left in the period, and center Creed Humphrey accidentally kicked him in the head as he appeared to rush toward his teammate's defense.

And when the injured running back went to the sideline to be evaluated, the medical table he was sitting on completely collapsed, leaving the Rutgers product nearly prostrate.

He did not appear to be injured by the table breaking, although he was eventually ruled out of the game due to concussion.

Before leaving, Pacheco found running room difficult to come by, as he only managed 26 yards on 11 attempts.

He was also credited with a fumble on a failed gadget play handoff to Mahomes, who was picked up by Las Vegas for an eight-yard touchdown.

Pacheco redeemed himself somewhat with a 12-yard touchdown in the second quarter.

But the Chiefs offense struggled that day as they lost 20-14 to the Raiders.

Mahomes also played below his usual lofty standards when he threw a pick-six to Jack Jones in the second quarter.

The loss dropped Kansas City to a 9-6 record with two games left to play this regular season.

They will face the Bengals and Chargers over the next two weeks in their attempt to capture the AFC West.

Some fans at Arrowhead Stadium had fun with it, though, as they bathed in a slime bath in honor of Nickelodeon's alternate broadcast.
