Natan Levy, a professional MMA fighter in the UFC lightweight division, had a message for Kanye West.
Speaking to MMA Fighting, he told Ye to "come see me, bro" if he had a problem with Jewish people.
Ye has made antisemitic remarks, which included praise for Adolf Hitler, in recent weeks.
Natan Levy, a professional mixed martial artist in the UFC lightweight division, had fighting words for Ye, formerly known as Kanye West, after a victory against Genaro Valdez at UFC Orlando on Saturday.
"Kanye West, if you've got a problem with me or my people, come see me, bro," he continued.
Ye has made a series of antisemitic remarks and posts in recent months. This week, he was suspended from Twitter after he posted an image of a Nazi swastika inside a Star of David.
Hours earlier, he praised Adolf Hitler and the Nazis in an interview with conspiracy theorist Alex Jones.
In October, the rapper and fashion designer had a tweet removed that said he was going "death con 3 on JEWISH PEOPLE."
Speaking to MMA Fighting, Levy said he had noticed an uptick in antisemitic hate being sent to Jewish people online since Ye made his racist comments. "Trust me, I've noticed it," he said, per MMA Fighting.
"I am Jewish, it's what I am, it's [the way] I was born," Levy continued. "I'm very proud of it and I will fight for it. I will fight for my people in the octagon, or wherever need be, and I will not stand for any antisemitism. I won't stand for any racism - not around me. Don't bully anyone around me, or I'm going to find you."
Other notable figures have condemned Ye for the antisemitic remarks, not least President Joe Biden.
