Drug tests for illegal performance-enhancing drugs and recreational drugs held by the Nevada State Athletic Commission returned clean for UFC 116 fighters. Headliners Brock Lesnar and Shane Carwin both tested clean as many were questioning sheer size of the two heavyweights.

Besides the headliners, and winners who are always tested following MMA events, random testing was also given to Chris Leben, Yoshihiro Akiyama, Chris Lytle, Matt Brown, Krzysztof Soszynski, Stephan Bonnar, Brendan Schaub, Kendall Grove, Gerald Harris, Ricardo Romero, Jon Madsen, George Sotiropoulos and Daniel Roberts. All of those tests also came back clean reported NSAC to MMAJunkie.com.
