Cris “Cyborg” Santos has been told by her heart doctor that a cut to 135 lbs. wouldn’t be realistic or healthy given her current physical condition, according sources.

Santos’ doctors refused to sign off on the idea of her cutting down to 135lbs. as it would not only adversely affect her health-wise, but it could even jeopardize her chances of carrying a child later in life, which is what convinced Santos to heed their advice.

With the reported signing of female MMA superstar Ronda Rousey and rival Miesha Tate as the UFC’s first ever female fighters, talk inevitably turned to the potential of bringing “Cyborg” in the fold,  and finally making a Rousey/Santos super-fight which has been building up over the last year or so.

Santos, currently serving her year-long suspension for use of banned substances, would be expected to be snapped up by the UFC once she’s eligible to compete once again, despite the UFC seemingly only focusing on the women’s 135lbs. bantamweight division right now. Any super-fight with Rousey would have to be at 145 lbs.

Should the UFC opt out of using “Cyborg” at 145lbs., it would be expected that she join the female-focused Invicta Fighting Championships.
