UFC dual champion Daniel Cormier isn’t the only one unhappy with the U.S. Anti-Doping Agency’ recent ruling on Jon Jones.

Ex-middleweight champ Luke Rockhold (16-4 MMA, 6-3 UFC), Cormier’s longtime friend and teammate, indicated he’s lost faith in the UFC anti-doping partner after Jones received a 15-month suspension.

“It’s a bit early,” he told reporters backstage at T-Mobile Arena, where he was serving as a guest fighter for UFC 229. “It’s a bit early. This USADA thing is getting kind of interesting.

“I’ve been dealing with them a little bit this week. I know DC’s been dealing with them a little this week. They should choose to attack the right people.”

Asked by MMAjunkie to elaborate on his interactions with USADA, Rockhold added, “just failures, and how they are attacking certain people for certain reasons when they should be doing their job in the first place – not going after the innocent.”

News of Jones’ drastically reduced suspension – a term reached after he went to arbitration on his second violation – prompted Cormier to declare USADA should stop visiting his house. Rockhold’s comments indicate the anti-doping agency did not oblige.

This week, Jones’ (22-1 MMA, 16-1 UFC) career was kicked back into gear when he was booked for a title fight rematch with Alexander Gustafsson (18-4 MMA, 10-4 UFC) at UFC 232. Although Cormier has yet to be stripped of the light heavyweight title he reclaimed when Jones flunked a drug test for their rematch at UFC 214, he will give up the title the moment Jones and Gustafsson square off.

Hot on the heels of Jones vs. Gustafsson 2, Cormier (21-1 MMA, 10-1 UFC) has agreed to defend his heavyweight title against Derrick Lewis (21-5 MMA, 12-3 UFC) next month at UFC 230. The fight is expected to tee up a retirement bout against ex-champ Brock Lesnar in 2019.

In August, Rockhold criticized USADA’s handling of Lesnar and Jones, who both were given one-year suspensions after failing drug tests in connection with UFC 200.

“When you get down to real business, these guys should be suspended for a long time,” Rockhold told MMAjunkie. “People are learning how to cheat the system. USADA’s got to step their game up and be what they were in the beginning.

“In the beginning, it seemed like they were doing their job. Now it seems like they’re owned. It’s sad to see, but hopefully it can correct itself, and we can get on the right path.”

Rockhold, who next faces fellow ex-champ Chris Weidman (14-3 MMA, 10-3 UFC) at UFC 230, has somewhat softened his stance on Lesnar, who stands to add several zeroes to Cormier’s bottom line if their proposed fight takes place. But he still doesn’t like the way things have played out.

Asked whether he still has faith in USADA’s work, Rockold said, “As of right now, it’s not too good.”
