Charles Oliveira, a former UFC lightweight champion, received a master's degree in Muay Thai and received a black armband.
“Today was a special day when, after hard work, I became the holder of a master’s degree in Muay Thai. I thank everyone who believed in my work,” the Brazilian fighter wrote on social networks.
Let us remember that Oliveira previously stated that he would like to have a rematch with Makhachev before Ramadan.
