Claressa Shields resigned with PFL ... and as the boxing superstar prepares to get back in the MMA cage, she says she's getting some tips from the one and only Conor McGregor.
"Conor McGregor inboxed me," Shields told TMZ Sports.
"Conor actually gave me some of the best advice today actually. He was just like 'Don't take away from your boxing. You need to get comfortable being on your back and comfortable with your wrestling.'"
Shields, who signed a multiyear deal with the MMA promotion this week, went 1-1 in the cage under the PFL banner in 2021.
