The Atlanta Hawks had to end practice early on Saturday because power forward Kris Humphries broke the backboard after dunked a basketball.
Atlanta was practicing at a Santa Monica high school before their game on Sunday with the Los Angeles Lakers. Players resumed practice on the other side of the gym.
According to the Atlanta Journal-Constitution, the Hawks will pay the high school for the damages.
The Minnesota native posted this picture on his Instagram following the accident, saying he's still washing the glass out of his hair.
The team even had fun with it by throwing basketballs to really make sure all the glass was on the floor.
