One of the bigger talking points coming out of the UFC's signing of Ronda Rousey was the potential of a Rousey vs. Cyborg superfight, possibly on the co-main of a PPV or a FOX card. It would be the biggest fight in women's MMA history, but that's taken a significant hit. Any possibility of Cris Cyborg dropping to bantamweight to face the current Strikeforce women's bantamweight champion Rousey has been shut down by her doctors. Via MMA Weekly:
Santos met with her doctors recently including a visit to the cardiologist to see about a possible move down to 135lbs, so that she could eventually and hopefully meet Rousey inside the cage to settle their long standing differences.
Members of Cris Cyborg’s camp confirmed to MMAWeekly.com on Tuesday that she visited with her heart doctor and was told that a cut to 135lbs would just not be safe based on her personal physical health. Her cardiologist stated emphatically that he would not sign off on a move down a weight class based on her current health.
The dangers to her body could also prohibit Santos from carrying a child later in life, and according to her camp, that was a risk the former Strikeforce champion was unwilling to make for any fight.
This is fairly important news, as the Strikeforce women's featherweight division was effectively destroyed after the currently suspended Cyborg tested positive for a banned substance earlier this year. There are no marquee names there other than Cyborg and Gina Carano, who hasn't fought in three years.
Rousey has been adamant that Cyborg drop to 135 to face her, so if the medical dangers prevent Cyborg from making the weight cut, it's no guarantee she even makes it into the UFC.
