The Oklahoma Thunder and Los Angeles Clippers faced off on Tuesday night in a heated Western Conference battle. Late in the second quarter, with the Thunder leading 44-39, Serge Ibaka tried to get a shot off from the baseline but Caron Butler wasn’t about to let that happen. Caron got up high and swatted Serge’s shot out of bounds, however there was an obstacle. That obstacle was referee Derek Richardson’s face. Check out how Derek took the ball to the face and got knocked down, but like a pro, he was quick to get back on his feet.
