NBA referee Courtney Kirkland tries to block a Kris Humphries free throw

Brooklyn Nets power forward Kris Humphries is slowly shaking his reputation as one of the NBA's punching bags, but on Wednesday night, he got clowned by NBA referee Courtney Kirkland. Humphries was readying to take a free throw against the Toronto Raptors, but apparently Kirkland wasn't as keen on the idea. So, Kirkland did what any self-respecting ref would never do, and jumped to swat Humphries as if he was Serge Ibaka.

That was just about the best defense that anyone played on the night against the Nets, who defeated Toronto, 94-88. Humphries put up just 11 points and two rebounds, as the Nets were carried by Joe Johnson, C.J. Watson and the resurgent Andray Blatche.

The Nets shot just 45 percent from the field, which paled in comparison to Toronto's 49 percent shooting, but Brooklyn hit 10-19 of threes, which was enough to push them to the win. That said, an NBA ref trying to punk Humphries for some unknown reason was the highlight of an altogether forgettable game.

Russell Westbrook throws down tomahawk jam against Hornets

The Oklahoma City Thunder have struggled a bit on Wednesday night against the New Orleans Hornets, but Russell Westbrook at least got the crowd and his bench perked up early in the game with a powerful tomahawk jam. Westbrook dribbled around a pick set by Nick Collison, knifed through the lane and elevated as Anthony Davis and Ryan Anderson stared helplessly.

That's been just about the only highlight for Westbrook so far, who has shot just 2-of-11 from the field midway through the third quarter. He's tallied eight points on the night, which is second on the Thunder behind Kevin Durant's 14. New Orleans hasn't fared much better in what has been an ugly, low-scoring game, but Ryan Anderson has put up 12 points on 5-9 shooting, while under-the-radar rookie Brian Roberts has scored 10 points.

In his second game back from injury, Davis has just two points, one rebound and one steal in 11 minutes of playing time.
