Bellator Fighting Championships announced yet another major offseason addition on Thursday with the signing of undefeated featherweight William Romero.

Romero, 27, one of Canada’s most talked-about young mixed martial artists, boasts an unblemished pro MMA record of 5-0. He was recently touted by MMAcanada.net — one of that country’s top MMA news sources — as “the real deal.” His most recent fight ended by KO after just 17 seconds.

“MMA fans north of the border know the name William Romero and now fans in the U.S. are going to have the chance to know it too,” said Bellator founder and CEO Bjorn Rebney. “We are excited to welcome him to our organization.”

Romero will compete in Bellator’s eight-man Season 2 featherweight tournament along with 12-1-1 Russian-born fighter Georgi “Insane” Karakhanyan and six yet-to-be announced 145s. Additional Bellator featherweight agreements will be announced next week.
