NBA player suffered a pretty serious injury after one of the dumbest tantrums

He --- and his team --- are going to pay dearly for the frustration.

Oklahoma City Thunder center Enes Kanter punched a chair in frustration during the second quarter of a game against the Dallas Mavericks, and he fractured his forearm in the process.

Kanter left the game, and it was soon reported he had fractured his forearm.

The injury could keep Kanter sidelined for up to two months.

The Thunder are currently sixth in the Western Conference, and Kanter's absence will certainly have a negative effect on their bench scoring. Kanter is averaging 14.4 points and 6.7 rebounds on 59 percent shooting in only 21.6 minutes per game off the bench this season.
