The Floyd Mayweather Jr. vs. Manny Pacquiao super fight rumours went into overdrive on Tuesday night (Wednesday night in Australia) when the top pound-for-pound boxers were in the same building watching the game between the National Basketball Association (NBA) game between the Miami Heat and Milwaukee Bucks.

The public appearance of Mayweather and Pacquiao has fuelled the hype of the super fight like never before as never in recent memory that both fighters were in the vicinity of each other. Account of the fans and reporters provided the scenes AmericanAirlines Arena in Miami, Florida on social media Twitter:

According to a report, via a tweet by AP writer Tim Reynolds, Pacquiao wasn’t supposed to be in the arena but the Filipino’s flight got cancelled so he was at the game. There is no indication that the appearance by both Pacquiao and Mayweather was pre-planned.

At halftime of the Heat-Bucks game, Mayweather and Pacquiao shook hands and talked. The Filipino confirmed later on that the pair exchanged numbers, according to Reynolds.

There is still no final deal with regards to the Mayweather vs. Pacquiao fight. But their latest public appearance together will add more speculations that there are indeed serious negotiations between the two boxers.

Pacquiao has reportedly given a deadline— until the end of January, or roughly four days— for Mayweather to finally accept the fight. Pacquiao was seen during his visit to the United Kingdom talking to another opponent prospect in Amir Khan and according to the Pacquiao camp, including Bob Arum and adviser Mike Koncz, the British boxer is a probable “Plan B” if Mayweather doesn't agree to a deal. As for Mayweather, there are reports that The Money Team is having conversations with Puerto Rican boxer Miguel Cotto for a fight on May 2, 2015.
