UFC responded to a Deadspin report of a shaky drug test from Vitor Belfort that came to light from 2012 after UFC 192 Saturday night.
"I think one of the things to keep in mind with this particular topic is, any suggestion or inference that there was a coverup in regards to that was categorically false," said Dave Sholler, UFC public relations head.
"That period of time with TRT is one that was tricky for everyone: For the UFC, for athletic commissions for athletes alike. I think when everyone came to a conclusion it didn't have a place in the sport and was outlawed in 2014, we were quick to make sure that we followed suit, as Nevada has said," said Sholler.
