Mike Tyson is helping kick off Shark Week with a fight to remember.

The boxing champ has joined forces with Discover Channel to bring the world Tyson Vs. Jaws: Rumble On The Reef.

Iron Mike, 54, will go 'toe-to-fin with one of the ocean's top apex predators' during the August 9th special, according to Discovery.

And Tyson - who was the undisputed world heavyweight champion from 1987 to 1990 - was certainly in fighting form in the show's first promo.

While training for the battle he knocks down a shark cage, then later punches a surfboard in half.

But his biggest challenge was having to blow up an inflatable raft.

'Shark Week is hard,' Mike said while shaking his head.

Then, the chiseled athlete-turned-actor warned: 'Someone's gonna get bit.'
