UFC superstar Conor McGregor is ready to pull a Floyd Mayweather Jr. The MMA fighter has challenged Tenshin Nasukawa to a bout before the summer.

McGregor raised eyebrows last night (January 6) on Twitter with the unexpected challenge.

Rather than stay mum, Tenshin has since responded to McGregor.

On New Year’s Eve, Conor hit up Instagram to reference Mayweather’s Tenshin bout payout and also announce he’s expecting a new baby in 2019.

Hours prior, Floyd managed to bank $9 million for a Japan fight.
