Combate Americas has landed a major MMA prospect, signing five-division world boxing champion Amanda Serrano to an exclusive multi-year contract.

Serrano is the only fighter in boxing history to win five world titles in five different weight classes, along with being the only Puerto Rican to accomplish the feat. She is 34-1-1 in her boxing career with 26 knockouts.

“We are excited to bring Amanda Serrano, one of boxing’s most exciting superstars into the Combate Americas familia, and look forward to placing her on a global stage that is the premier sports property in 21 Spanish speaking countries worldwide,” said Combate Americas CEO Campbell McLaren.

The promotion added that Serrano will likely make her MMA debut this March from La Jaula. No date has been set.

While she enters into MMA, Serrano is not finished boxing, as she’ll remain working with DiBella Entertainment on her career there. Her co-manager is former UFC champion Miesha Tate.

Serrano captured her first boxing title at the age of 22 when she knocked out Kimberly Connor in 2011 for the IBF super featherweight crown. She has signed claimed titles from bantamweight to lightweight, including a November first round TKO vs. Marilyn Hernandez.

“Thanks (Combate) for the opportunity to be part of your amazing company,” Serrano posted on Twitter. “My team especially Miesha Tate who help make the decision an easy one with her knowledge of the sport. Let’s get it!”

Last July, Serrano defended her WBO bantamweight title with a third round TKO of Edina Kiss. Her only career loss to date came in 2012 via decision to Frida Wallberg in Sweden.
