Rapper Lil Wayne tried to fight a member of Marcos Maidana’s entourage after the boxer’s bout with Floyd Mayweather Jr. on Saturday, according to a report.

The incident occurred after the conclusion of Maidana’s loss by decision at MGM Grand Hotel & Casino in Las Vegas, TMZ Sports reports. Sources revealed that the near-brawl stemmed from Wayne’s reaction to being hit by a thrown water bottle.

According to sources, Wayne, who attended the fight as a member of Mayweather’s entourage, was exiting the boxing ring when he was hit in the shoulder by a water bottle. The 31-year-old rapper reportedly believed that Maidana’s trainer, Robert Garcia, was responsible for throwing the bottle.

A video of the post-fight altercation shows a furious Wayne being restrained by his camp as he attempts to confront Maidana’s trainer. Several individuals manage to separate the two before they could come to blows, and the night proceeds without further incident, TMZ Sports reported.

Lil Wayne’s dispute with Garcia wasn’t the only moment of controversy surrounding the Mayweather-Maidana bout. In the hours before the fight, Mayweather’s camp threatened to walk away from the event due to concerns regarding Maidana’s boxing gloves. The 30-year-old planned to use a type of boxing glove that was not approved by the Nevada State Athletic Commission, USA Today reported.

Mayweather was reportedly concerned with the lack of padding around the glove’s knuckles, and got into a heated argument with Garcia over the disparity. However, the two sides came to an unspecified agreement and the fight proceeded as scheduled.

Despite a close bout in which Mayweather suffered a cut for the first time in his boxing career, the undefeated boxer earned his 46th victory by majority decision (114-114, 117-111, 116-112), MMAFighting.com reports.
