Fight week has begun in Las Vegas after Conor McGregor and Floyd Mayweather arrived in Sin City Tuesday ahead of Saturday's highly anticipated fight at T-Mobile Arena.
Mayweather was the first to make his grand arrival at Toshiba Plaza and spoke with media and fans before he and his large entourage left. As they were leaving, they crossed paths with McGregor's team.
A lot of shouting, along with some pushing and shoving, ensued as McGregor had to be pulled away from the scrum.
Part of the clash was between McGregor and former sparring partner Paulie Malignaggi, who will be part of Showtime's broadcast team for Saturday's fight. Malignaggi stopped working with McGregor after the MMA fighter posted a video that showed McGregor knocking Malignaggi down during a sparring session.
During Tuesday's shouting match, Malignaggi repeatedly told McGregor to, "bring your balls."
