KAMARU USMAN has teased putting on two-and-a-half STONE to fight former light-heavyweight champion Jan Blachowicz.
Usman, currently the title holder at welterweight, faces Leon Edwards in a defence of his belt on August 20.
But he has hinted at jumping two divisions afterwards as he sized up Blachowicz, 39, on Saturday night.
Usman posted: "Nothing I can’t Handle… But first the English."
The Nigerian-American currently reigns over the 170lb division at 12st 1lb.
But he has his eyes on becoming a two-division champ, even though he is close friends with middleweight king Israel Adesanya, 32.

It means Usman has targeted the 205lb light-heavyweight division of 14st 6lb, where Jiri Prochazka, 29, holds the belt.
And Prochazka welcomes it, telling The Schmo: "I like to challenge myself. And this is good challenge because it is another weight class.
"I don't believe in weight classes. Because every time it's just about the strongest man on the planet. That's what I'm looking for."
Prochazka won the belt by dramatically beating Glover Teixeira, 42, in the last round, with the Brazilian calling for a rematch.

“I have to make a decision about next fight," Prochazka said.
"And I’m thinking about, to give offer to, for Glover for a rematch, or to challenge to Jan. Because Jan is for me bigger challenge.
"But, I think Glover, he made a great performance in that fight and I have to say to him, huge respect for that. So, we will see.”
