Berto, 33, was undefeated until he fought Victor Ortiz in 2011, a loss he avenged in 2016. In recent years he's also suffered losses to Ghost Guerrero, Jesus Karass, Pretty Boy Floyd, and Shawn Porter.
Berto's dad was a kickboxer. His sister Revelina and brother Edson are both MMA fighters. I'm sure the UFC would love to add him but I'm guessing he wants to jump into a big money fight not start from the bottom.
