All 22 fighters who fought at UFC 162 competed clean, according to the Nevada state athletic commission, which released the results of drug screening to the media on Friday.

According to NSAC executive director Keith Kizer, everyone on the card was tested for steroids and drugs.

For heavyweight Dave Herman, that included an extra test, as he was mandated to pass a surprise screening in order to receive his license to fight on the July 6 event at the MGM Grand Garden Arena. He tested clean, but lost via knockout to Gabriel Gonzaga in just 17 seconds.

An MMA Junkie report noted that NSAC issued a therapeutic use exemption for the prescription medication Suboxone to middleweight Chris Leben, who fell in a split-decision to Andrew Craig. Suboxone is generally used in the treatment of opioid dependence.

In the night's main event, Chris Weidman ended Anderson Silva's storied UFC middleweight title reign, shocking him with a second-round knockout.
