After a long and often contentious hearing, the Nevada State Athletic Commission today handed down its harshest punishment on a fighter to date, voting unanimously to suspend Nick Diaz for five years after a positive marijuana test in connection with his decision loss to Anderson Silva at UFC 183.

Diaz (26-10 MMA, 7-7 UFC), 32, was also fined 33 percent of the $500,000 “show” purse he received for his Jan. 31 headliner at Las Vegas’ MGM Grand Garden Arena, which amounted to $165,000, and attorney’s fees and costs in connection with his hearing. It was his third suspension for marijuana.
