Well, that's certainly a relief.

Nevada State Athletic Commission (NSAC) Executive Director Keith Kizer today (Nov. 9, 2012) informed MMAmania.com that Shane Carwin and Roy Nelson have both tested negative for steroids and diuretics.

The two coaches for The Ultimate Fighter (TUF) 16, who are expected to collide for a spot in the 265-pound pecking order at the show's live finale on Dec. 15, 2012 in Las Vegas, Nevada, were targeted for random drug testing back in mid-October.

They passed.

It wasn't that long ago when the commission popped heavyweight striker Alistair Overeem for elevated testosterone, who was administered a random drug test a few weeks ahead of his UFC 146 title fight opposite Junior dos Santos. "Demolition Man" was denied a license to fight and will be sidelined for the remained of this year.

The results for the UFC's TUF guys will undoubtedly calm the nerves of the promotion's higher ups.

Carwin was linked to a pharmacist busted in 2010 for a nationwide conspiracy to illegally sell anabolic steroids made in Mobile, Alabama; however, "The Engineer" has never failed a drug test since making his Octagon debut at UFC 84 back in 2008.
