Haye: I've signed to fight Fury

It wouldn't be a for a world title or even an official eliminator, but an all-British showdown between former heavyweight titleholder David Haye and contender Tyson Fury would be a big deal for the heavyweight division, especially in Great Britain.

Haye (26-2, 24 KOs) and Fury (21-0, 15 KOs) are both extremely polarizing, cocky and have big mouths. It would be akin to a heel-versus-heel match in the WWE, but it would probably be a fun matchup while it lasted.

The fight is on the table, and Haye announced via Twitter on Monday that he has signed on the dotted line.

"I've just signed to fight Fury on Sept. 28," Haye tweeted. "Let's hope he finally agrees [and signs today] and he doesn't keep delaying. Word around 'Camp Fire' is Fury is looking to duck me and fight Tony 'The Tiger' [Thompson]. Let's hope they are just to rumors."

Thompson knocked out British heavyweight hopeful David Price in the fifth round on Saturday -- his second KO win in a row against Price -- and then called out Fury.

Haye also posted a video on Instagram in which he is seen signing a piece of paper, supposedly the fight contract.

"We've re-jigged the contract so he's nice and happy. All done," Haye said on the video.

Haye tweeted later on Monday: "It appears Dyson Furry has lost his pen and/or balls! He's hiding under a rock now it's time to put pen to paper! #Run&Hide #Coward #Chump."
