There will be two ring announcers when Floyd Mayweather takes on Manny Pacquiao in the richest fight in boxing history - Michael Buffer will introduce Manny Pacquiao, and Jimmy Lennon Jr will introduce Floyd Mayweather Jr.
It is because of the different broadcasters the boxers are on - Pacquiao is on HBO with Buffer, and Mayweather on Showtime with Lennon Jr.
HBO ring announcer Buffer and Showtime's Lennon Jr also did this 13 years ago.
Buffer and Lennon previously shared announcing duties back in 2002 - the Lennox Lewis-Mike Tyson heavyweight championship fight. Buffer introduced Lewis, while Lennon introduced Tyson.
Lennon Jr: 'It's Showtime!'
Buffer: 'Let's get ready to rumble!'
The welterweight clash will be most lucrative fight in boxing history, with the combined purse for the bout expected to top $300m (£201m).
Unbeaten Mayweather, 38, is an 11-time, five-weight world champion, while the Filipino Pacquiao, 36, has won versions of the world title at a record eight different weights.
WBA and WBC welterweight titleist Mayweather's record stands at 47-0, while WBO champion Pacquiao has lost five of his 64 fights, with two draws.
