The New York Mets’ Edwin Díaz was taken off the field in a wheelchair after injuring his right knee celebrating Puerto Rico’s victory over the Dominican Republic in the World Baseball Classic on Wednesday night.

There was no immediate word on how severely Díaz was hurt — the Mets said he will undergo more tests Thursday. But the way his teammates stood around him in shock didn’t look encouraging.

The injury was exactly what big league teams and their fans fear the most about the WBC.

Díaz signed a $102 million, five-year deal in November.

“Those things, they can happen to anybody at any given time,” Los Angeles Dodgers star outfielder Mookie Betts, who was playing for the United States when Díaz was hurt, told The Associated Press.

“You can always try to place blame on the WBC, but that was just a freak accident that could happen to anyone at any given time,” he said.

Díaz was swarmed by teammates after pitching a perfect ninth inning in a 5-2 win that clinched Puerto Rico a spot in the WBC quarterfinals. The group was jumping together in the infield when the right-hander collapsed to the ground, and he immediately reached for his right leg.

Díaz was in tears and did not put any weight on his right leg as a coach and trainer helped him limp toward the dugout.

Díaz’s brother, Reds pitcher Alexis Díaz, was also crying as Edwin was put in a chair and wheeled away. Mets teammate and Puerto Rico shortstop Francisco Lindor stood nearby with his hands on his head.
