Let the speculation begin.
Before Manny Pacquiao entered the ring to face Jessie Vargas at the Thomas & Mack in Las Vegas, a very special guest arrived to get a firsthand look at the Filipino.
Mayweather entered the arena right before Oscar Valdez' 7th round TKO over Hiroshige Osawa and took his seat at ringside.
The retired Mayweather's arrival immediately fuels speculation that there could be a rematch with Manny Pacquiao on the horizon. The two engaged in a blockbuster fight in May 2015 that smashed records and earned bother fighters career high paydays. Mayweather won that fight handily by unanimous decision. But there has been speculation as to how the fight would have went with Pacquiao stating he injured his shoulder heading into that fight.
Although Mayweather said he was happy with retirement, there's a reason why they call him "Money."
