Diaz stepped away from fighting after a loss to former middleweight champion Anderson Silva in January 2015 that was later ruled a no contest after Silva and Diaz failed post-fight drug tests. He returned to the octagon after six years in a rematch against former welterweight champion Robbie Lawler. Diaz knocked out “Ruthless” at UFC 47 in April 2004, but Lawler scored the stoppage in the rematch, finishing Diaz in the third round.
