Frustrated with how he was playing against the Sacramento Kings on Wednesday night, Los Angeles Clippers guard Austin Rivers vented by hitting a chair, breaking it and the seat cushion. Perhaps wanting to get rid of the damage he created, Rivers then casually tossed the cushion into the stands. Unfortunately, Rivers hit a female fan in the face with the cushion.

Due to his careless actions, the NBA fined Rivers $25,000 on Thursday. 

Via PBT's Dan Feldman, here is the video of Rivers hitting the fan:

Rivers had a subpar game against the Kings on Wednesday night, scoring 3 points in 16 minutes. But that isn't a good reason to hit a fan with a seat cushion, which may sound harmless. However, according to CSNBayarea.com's James Ham, Rivers actually knocked out one of the woman's contact lenses. Not a great look for Rivers.
