In his first reaction since Manny Pacquiao called him out on Saturday night in Macau, Floyd Mayweather Jr. (or someone from his team) posted a video of Pacquiao getting knocked out by Juan Manuel Marquez on the boxer's official Facebook page. The video, possibly fan made, shows repeat clips of Pacquiao getting dropped and knocked out by Marquez from their fourth meeting in 2012.

Following his lopsided decision win over Chris Algieri, Pacquiao publicly challenged Mayweather to a 2015 mega-fight. Top Rank's CEO Bob Arum, who promotes Pacquiao, is speaking with CBS CEO Les Moonves to get Mayweather on board with the fight. CBS is the parent company of Showtime, who have Mayweather under an exclusive contract.
