A Miami Dolphins NFL star has reportedly had 'an emotional breakdown' after his team-mates played a practical joke on him.
Jonathan Martin went AWOL from the team after an incident at the club's canteen on Monday.
According to reports, all of his team-mates got up and left when he sat down to have his meal with them. They then started joking about him being sick.
Martin 'flipped out' after the incident, smashing a food tray on to the ground before storming off.
Nobody on the team has seen him since.
Respected NFL reporters Jay Glazer of Fox Sports and Jeff Darlington of the NFL Network tweeted more details about the incident.

Jonathan Martin left Dolphins' facility on Monday, immediately sought outside assistance after what a teammate called "emotional breakdown." — Jeff Darlington (@JeffDarlington) October 30, 2013
Jonathan Martin is now spending time with family. Team and players are mostly out of touch with his situation. My thoughts are with him.

Martin, 24, is playing in the NFL as an offensive tackle, in the second season of a four-year, $7.8 million contract.
During his first season he played right tackle but was moved to 'the blind side' or left tackle for the first six games of this season.
This was considered a promotion as left tackle is one of the most important, and highly paid, positions in American football because that position is charged with protecting the quarterback.
The Dolphins won their first three matches of the season but then lost three in a row. The Dolphins then traded for a new right tackle and moved Martin back to the right side.
According to the Miami Herald, Martin "wasn't thrilled with the move, but a source believes that isn't the reason for his breakdown this week."
The team's only response to the story has been to confirm Martin is a day-to-day doubt for them due to "illness".
