Floyd Mayweather Jr. is changing his tune about a potential rematch with Manny Pacquiao.
Speaking to TMZ Sports, Mayweather said he "don't give a f--k about what's going on with Pacquiao."
This is a shift for the 50-0 boxer, who wrote in an Instagram post last month that a second fight with Pacquiao was on the horizon.
"I'm coming back to fight Manny Pacquiao this year," Mayweather wrote at the time.
