Oklahoma City Thunder centre Enes Kanter is facing a lengthy spell on the side-lines after fracturing his forearm during the Thunder's win over the Dallas Mavericks.
During the second quarter, a frustrated Kanter headed to the bench following an offensive foul call and unleashed on an innocent chair, smacking it with his right hand.
Kanter was then seen holding his right arm and later headed to the locker room and did not return.
Reports suggest the chair was not injured during the vicious attack.
It is not the first time a player has punched a chair this season, with Sacramento Kings centre DeMarcus Cousins punching a chair against the Golden State Warriors.
It will be a big blow for the Thunder as Kanter is averaging 14.6 points and 6.8 rebounds per game off the bench this season.
Thunder coach Billy Donovan said post-game it is unknown when Kanter will return from injury.
The injury could see Kiwi Steven Adams get more minutes for the Thunder who have a limited big-man rotation.
The Thunder beat the Mavericks 109-98 for their third staight win.
