Chiefs press conference ends abruptly after parts of the CEILING start falling down on journalists while defensive tackle Chris Jones reflects on defeat by the Bills

A Kansas City Chiefs press conference was brought to an unexpected halt on Sunday night when parts of the ceiling began falling down on reporters.

After their controversial 20-17 defeat by the Buffalo Bills, Chiefs defensive tackle Chris Jones was facing the media when the incident took place.

Footage on social media shows Jones suddenly stopping and looking upwards while answering a question, before loud crash and bangs are heard as a huge part of the ceiling fall to the ground.

One journalist appeared to have moved out the way just in time, and the rest in the room eventually saw the funny side as the press conference ended in abrupt and unusual fashion. 

At one stage of the video, the camera pans to a huge hole in the ceiling where part of it has fallen to the ground.

It marked an all-round day to forget for Kansas City, who slumped to a second straight defeat against Buffalo.

On a night which saw Taylor Swift head to Arrowhead to cheer on Travis Kelce, Chiefs quarterback Patrick Mahomes was left seething after an offensive offsides call negated a late touchdown for them on the day

Mahomes found Kelce over the middle of the field with 1:20 remaining, and the tight end lateralled the ball to Kadarius Toney, who scampered into the endzone to give the hosts a lead.

But Toney had lined up in the neutral zone before the play, drawing a flag and ultimately erasing the score, which would have given Kansas City a 23-20 lead pending an extra point.

Mahomes' last gasp attempt to keep the Chiefs' drive alive moments later fell incomplete, and the quarterback was absolutely livid on the sideline. 

He slammed down his helmet and appeared to yell at a referee, 'We played our f****** a**** off and you call offensive offsides!'

Swift and a devastated-looking Kelce were spotted holding hands as they left Arrowhead together on Sunday night, after the pop superstar flew halfway across the country to watch him lose a second straight game.

In a picture of the loved-up pair, Swift can be seen trying to console a disappointed-looking Kelce, who had showered and put on his pre-game fit to head home.
