(CNN) - Former heavyweight boxing champ Mike Tyson will kick off Discovery Channel's Shark Week by taking on a new opponent.
The network says he will square off underwater against a shark, in the name of research.
The special is billed as "Tyson vs. Jaws: Rumble on the Reef."
A promo shows him lifting weights, breaking a surfboard, knocking down a shark cage and trying to blow up an inflatable raft.
There's no word on exactly how Tyson and the shark will interact or what this face-off will entail.
The network says no sharks were injured.
The special airs on the first day of Shark Week on Aug. 9.
