Reigning Ultimate Fighting Championship (UFC) flyweight champion, Henry Cejudo, is giving bantamweight champion, TJ Dillashaw, the opportunity that former division kingpin, Demetrious Johnson, refused to entertain.

“The Messenger” has agreed to welcome Dillashaw to the 125-pound weight class in a champion vs. champion “super fight” that could crown the next “champ-champ” on Jan. 19 in Brooklyn. Not only would that require Dillashaw to win, but also to make weight.

Cejudo’s manager, Ali Abdelaziz, is not feeling overly optimistic.

“I don’t think T.J.’s going to make weight and if he misses weight by .1 pounds, Joseph Benavidez is going to fight, we’re going to give Joseph a shot,” Abdelaziz told MMA Fighting. “Because I personally don’t think he’ll make it. If he makes it, he’s going to be weak, fragile, and he’s going to have a long, long night with the champ. He’s a good fighter, but he can’t fight at the pace Henry’s going to fight him at 125. He doesn’t have the speed to fight Henry.”

Champion vs. champion fights are all the rage these days.

It helps that Cejudo doesn’t have much to work with at 125 pounds, outside of this rematch, thanks to the recent bloodletting that sent a handful of flyweights into unemployment. Whether or not you can blame ONE Championship for that all depends on who you ask.

It’s not like Dillashaw has a bevy of fresh faces, either, but UFC President Dana White has already called the winner of Marlon Moraes vs. Raphael Assuncao at UFC Fortaleza the bantamweight No. 1 contender.

Still lots of pieces to this two-division puzzle.
