Six fighters from the all-heavyweight main card of UFC 146 gathered in Las Vegas for a press conference on Tuesday. According to HD Net's Ron Kruck, the Nevada Athletic Commission took advantage of all six being in town by stopping them for a pre-fight drug test.

Roy Nelson (right), who will fight Antonio Silva (left) had a picture snapped with his opponent and heavyweight champ Junior dos Santos as they waited for, as Nelson put it, "results from our pee tests." Dos Santos will fight Alistair Overeem to defend his belt for the first time since winning it from Cain Velasquez.
