A fan tried to sneak in a jab at Austin Rivers before Saturday’s game against the Thunder at Toyota Center, but the Rockets guard shut it down quickly.

Rivers walked by the man in the tunnel, where a number of fans and media members were standing. The fan had this to say as Rivers approached him:

“Your dad sucks at coaching,” the fan joked.

Rivers, however, was not having it. He confronted the fan, who went silent quickly.
