LOS ANGELES -- The USADA's impending ban on post-weigh-in IV hydration remains a hot topic among fighters on the UFC roster.

Top UFC middleweight contender Luke Rockhold and former WEC featherweight champion Urijah Faber both rehydrate via IV following their weigh-ins, and both are skeptical about the new policy.

Rockhold, in fact, believes the UFC should take things in a completely different direction. Rockhold believes the UFC should both facilitate and oversee the administration of IV for fighters who choose them at the weigh-ins.

"I think the UFC should take the initiative to administer IVs immediately backstage, and bring everyone to optimal hydration for optimal performance," Rockhold, who challenges Chris Weidman for the middleweight title at UFC 194, said at a recent lunch. "That's what you want, right?"

The way Faber sees it, once the IV ban goes into effect, we'll see a mass migration upward in weight class on the UFC roster. For his part, Faber says he's going to attempt his fight at bantamweight with Frankie Saenz at UFC 194 without an IV, then decide whether to go back to featherweight.

"I'm going to do it without the IV and see how I feel," Faber said. "It might be good, I might have to run a lot more than usual, I have to run every day, which isn't how I want to spend all my time training. I'll wait and see. I think at '45 without an IV, Aldo goes up, McGregor goes up, a bunch of other guys go up. Chad will be fine, he's not huge for the weight class. It's going to be interesting. I'm so curious if that's going to stick. "

USADA's concern is that IV usage can mask the use of performance-enhancing drugs. Fighters could potentially face a two-year suspension for violating the policy, which goes into effect on Oct. 3.
