UFC's Diaz fined, out 1 year for Nevada pot test

LAS VEGAS (AP) -- Ultimate Fighting Championship competitor Nick Diaz is being fined $79,500 and banned from fighting until next February for testing positive for marijuana use following a fight in Las Vegas.

Nevada Athletic Commission executive Keith Kizer said the fine imposed following a Monday hearing amounts to 30 percent of Diaz's $265,000 purse and bonus following his Feb. 4 UFC welterweight title loss to Carlos Condit. The one-year suspension dates from that fight.

Diaz and his lawyer, Ross Goodman, failed to convince commissioners that Diaz had a prescription from a doctor in California to use medicinal marijuana for treatment of attention deficit hyperactivity disorder.

Diaz also lost his license for six months and was fined $3,000 by the commission after another positive marijuana test following a win in 2007.
