For those of you mixed martial arts (MMA) fans optimistic enough to believe a Cristiane Justino vs. Ronda Rousey "super fight" will eventually take place, I present to you yet another obstacle standing in the way of "Cyborg."

The upcoming ban on intravenous hydration.

Under new guidelines from the United States Anti-Doping Agency (USADA) -- retained earlier this year to oversee Ultimate Fighting Championship (UFC) drug testing -- fighters will no longer be able to recover from weight cuts by way of needle and plastic bag.

Sorry, wimps.

Said policy will likely send a lot of fighters to heavier divisions, or perhaps in the case of Justino, keep her right where she is. That's according to comments the Brazilian made during her Invicta FC media scrum earlier this week in Las Vegas, Nevada (via MMA Fighting), calling the "bad" policy a "problem" in her quest to make 135 pounds.

"I want to be healthy. I know fighting and [being] famous, [the] belt, it's for now. At the end of the day, you're getting older, I don't want to be sick. I want to have kids. I'll try 100 percent, I'll try for all my fans to make this (Rousey) fight happen and I know I can sleep [at night] and say I did my 100 percent to make this fight happen. I already have a lot of problems about cutting weight, dieting and a lot of things. It's not healthy what we do. Drop to 135? And be healthy? OK, of course."

Doctor's orders!

Rousey, who previously competed at featherweight and once offered to move back up for a "super fight" against Gina Carano, refuses to budge from her current weight because Justino failed a post-fight drug test under the Strikeforce banner back in 2012.

While "Cyborg" is currently under contract with ZUFFA, she must still get past Faith Van Duin this Thursday night (July 9, 2015) in the Invicta FC 13 main event in "Sin City." Rousey, meanwhile, has another Brazilian she needs to worry about next month in Rio de Janeiro, Brazil, when she defends her 135-pound crown against Bethe Correia in the UFC 190 pay-per-view (PPV) main event.

"I hope Bethe kicks her ass," Justino said. "I think [that], I want [that]. I think [Correia is] a good fighter, good boxing. I think it's a good fight for Ronda."

Not as good as Rousey vs. Cyborg, but it will have to do.
