Floyd Mayweather hinted at a possible rematch against Conor McGregor in the immediate aftermath of the Irishman’s explosive return to the octagon at UFC 246.

McGregor was making an eagerly anticipated comeback after 15 months away and did not disappoint, needing only 40 seconds to stop American veteran Donald Cerrone at the T-Mobile Arena.

It was at the Las Vegas venue where McGregor crossed over to the boxing world for a showdown against pound-for-pound king Mayweather, who extended his perfect professional record to 50-0 with a late stoppage over the Dubliner in 2017.

However, Los Angeles Lakers superstar LeBron James wrote: “Welcome back Champ!! @TheNotoriousMMA.”

Joel Embiid of the Philadephia 76ers added: “WOW THAT WAS QUICK.”
