All fighters selected to undergo drug testing at last month's UFC 102 event successfully passed their tests.
Six of the night's 22 fighters, including headliners Antonio Rodrigo Nogueira and Randy Couture, were chosen for testing.
Other tested fighters included Chris Leben, Aaron Simpson, Todd Duffee and Evan Dunham. (Because Leben was fighting for the first time since a failed drug test at UFC 89, he underwent testing before and after UFC 102.) Link
