The Nevada Athletic Commission filed temporary suspensions on Anderson Silva, Nick Diaz and Hector Lombard Tuesday during their monthly meeting.

Silva and Lombard tested positive for performance-enhancing drugs, while Diaz was popped for marijuana.

Full hearings will be scheduled for all three in the near future.

The commissions unanimously approved the suspensions.

Silva also failed his pre- and post-fight drug tests prior to defeating Diaz at UFC 183. Lombard’s failed test came after UFC 182 in January.
