You have to feel bad for Ricky Rubio. The Timberwolves guard thought he had an easy rebound in the fourth quarter against the Toronto Raptors on Wednesday, but Rubio was very, very wrong.

Coming out of nowhere, DeMar DeRozan skied above Rubio, grabbed the ball off the rim and threw down an emphatic one-handed slam right on the Timberwolves guard's head:

Rubio clutching the back of head after the fact makes DeRozan's dunk that much more vicious as his slam literally added insult to injury.
