Yoel Romero and the UFC have parted ways, his manager, Malki Kawa, told Ariel Helwani of ESPN.
Romero had three fights remaining on his contract with the promotion, sources told Helwani.
"While we didn't expect Romero's time in the UFC to end like this, we are grateful for the opportunities (UFC president) Dana White, (general counsel) Hunter Campbell, and (matchmaker) Mick Maynard gave him over the years," Kawa said. "He's ready to move on now and resume his career and we are already talking to other promotions as we speak."
The 43-year-old last fought in March against Israel Adesanya and was defeated by unanimous decision, which extended his losing streak to three fights.
The "Soldier of God" debuted in the UFC in 2013. He won his first eight bouts but lost four of his last five.
Romero fell short in four opportunities to win the middleweight title throughout his UFC career.
