For the third time this week, Conor McGregor is under fire on social media for comments viewed as racially insensitive as he tries to provoke Floyd Mayweather Jr. during their "Money Fight" world tour.

At each of the first two stops of the tour promoting the Aug. 26 fight — Tuesday in Los Angeles and Wednesday in Toronto — McGregor told Mayweather to, "Dance for me, boy."

McGregor's latest comment came during an interview conducted by Jimmy Kimmel Live's Guillermo Rodriguez that was broadcast Wednesday. Rodriguez asked McGregor who would win a fight between McGregor and Sylvester Stallone's character in Rocky III.

"Rocky III?" McGregor said. "I'm trying to remember which one was Rocky III. Was that the one in the celebrity gym? I can't remember if that's the one with the dancing monkeys or not."

Users on Twitter have speculated that McGregor was referring to a scene from the movie in which several African-American boxers were training in a gym.

Mayweather addressed racism during an interview with TMZ Sports earlier this week.

"Racism still exists, but you know, I try to take something negative and turn it into something positive," Mayweather said. "A lot of people say that Conor McGregor is racist, but I'm not worried about that."

The third stop of the four-city tour is in New York on Thursday night.

McGregor's comments this week follow other controversial moments during his UFC career.

Leading up to UFC 202 last year, McGregor referred to the the Diaz brothers as "(expletive) those cockroaches” and called Nate Diaz, his opponent, "a little cholo from the hood."

In an appearance to promote UFC 189 where he'd face Brazilian Jose Aldo, McGregor said he wanted "to turn (Aldo's) favela into a Reebok sweatshop," according to Yahoo Sports. Favela is a term for disadvantaged areas in Brazil.
