UFC's Nick Diaz -- 5-Year Suspension for Failed Drug Test

Nick Diaz might never step in the Octagon again -- the UFC fighter just got slapped with a 5 year suspension for failing a drug test.

The Nevada Athletic Commission handed down the suspension, and also a $150k fine. He failed the test -- reportedly for marijuana -- earlier this year after his fight Anderson Silva in UFC 183.

Diaz will be 36 when the suspension ends, which would certainly make it difficult for him to make a comeback.
