The drug testing of 24 fights from UFC 146: Dos Santos vs. Mir were all clean, according to information obtained by MMAjunkie.com from the Nevada Athletic Commission.

Keith Kizer, executive director of NAC, confirmed the clearing of the tests in an e-mail.

UFC 146 featured Junior dos Santos defeating Frank Mir in a bout for the UFC heavyweight title. The testing was of importance because it knocked Alistair Overeem from the planned bout several months ago following a pre-fight drug test that came back positive.
