UFC star Kamaru Usman teases two and a half STONE weight gains to jump two divisions, fight ex-champ Jan Blachowicz

KAMARU USMAN teased that he would put on two-and a-half STONE in order to face Jan Blachowicz, former light-heavyweight champion.

Leon Edwards, the current title holder at welterweight will face Usman in a defense of his belt on August 20,

He has hints at jumping two divisions after he's sized up Blachowicz (39).

Usman wrote: "Nothing that I can't handle... But first, the English."

At 12 st 1lb, the Nigerian-American reigns supreme over the 170lb division.

He has his sights set on becoming a two division champ even though he is close to Israel Adesanya (32), middleweight champion.

This means Usman has aimed for the 205lb heavyweight division of 14st 6lb. Jiri Prochazka (29) holds the belt.

Prochazka is open to it, telling The Schmo that she likes to challenge herself. This is a good challenge, as it's another weight class.

"I don't believe in weight classes. It's not about the strongest man on earth every time. That's what I want.

Prochazka, 42, won the belt after beating Glover Teixeira (42), in the final round. The Brazilian demanded a rematch.

Prochazka stated, "I must make a decision about the next fight."

"And I'm considering, to make an offer to Glover for a match or to challenge Jan. Jan is for me a bigger challenge.

"But, I think Glover made a great fight in that fight. I have to give him huge respect. We will see.
