Santos, 28, appeared on AXS TV's "Inside MMA" to discuss her plan to defeat Rousey by the end of this year.
In reference to Ronda’s statement that I am looking for a payday so that I can retire, you’re right, I am looking for a payday to retire you like I did Gina Carano. But to show it’s not only about money, I challenge you to a fight – winner takes all. Or better yet let’s fight for FREE. ANYTIME! ANYWHERE! Ask your daddy Dana to make it happen. My English is not that great, so sorry if I was misunderstood. I didn’t literally mean I would die if I made 135. What I meant was that my doctor recommended that I did not fight the rest of my career at 135, which is what the UFC wanted.
Santos plans to drop down for a test run at 135 pounds with a fight against Invicta FC's bantamweight champ Lauren Murphy.
Since Santos is already scheduled for a Muay Thai fight in March, her 135-pound Invicta FC fight could realistically happen sometime this summer.
If Santos is able to slip past Murphy, she could fight Rousey at the UFC's year-end show this December.
"You have fought 154 in the Olympics and 145 in MMA. You can meet me at 140 easier than for me to go down to 135," Santos said of Rousey. "The only reason you want the fight at 135 is because you feel that is your only chance because you hope the weight cut will affect me. You guys say I’m irrelevant, yet watch my highlights. The true MMA fans not only know me, but know I’m the best. Sad that you give the true MMA fans no recognition by saying that they don’t matter.
"I’m currently training to fight at 145 on March 28 and in early May. My team has hired a medical doctor to help me make 135. I plan to challenge and win the Invicta 135 Championship in the summer and challenge you, champion to champion, for your 135 belt in December."
Analysis: Four things need to happen for the Santos vs Rousey fight to go down at the end of this year.
First, Rousey needs to beat Sara McMann at UFC 170. Then, she'll have to defeat Alexis Davis this summer. Additionally, Santos will need to defeat Lauren Murphy under the Invicta FC banner. Next, the UFC will need to extend Santos a contract.
If all four things happen, then Santos could fight Rousey in a year-end UFC fight.
"Now I know critics will say 'I thought you said you would die if you made 135.' All I’m promising is that I will give 100 percent to try to get to 135 to make this plan happen," Santos said. "If I do, I will still listen to my doctor’s advice and fight no more than three times at 135: first to win the Invicta belt, the second time to kick your ass and the third time to kick your ass again so that the world can see it wasn’t luck. You can even have me tested every week up to the fight. That way you will not have an excuse after I kick your ass.”
