Olympic swimmer Michael Phelps is known as a killer in the pool, but can he defeat a great white shark?
Viewers will find out next month when Discovery airs a race between Phelps and a shark as part of its annual Shark Week event.
"[Phelps] has one competition left to win," the network says in a statement announcing the showdown. An event so monumental no one has ever attempted it before. The world's most decorated athlete takes on the ocean's most efficient predator: Phelps vs. Shark--the race is on!"
The broadcast, titled Phelps vs. Shark: Great Gold vs. Great White, will air on July 23 at 8 p.m. ET/PT.
Presumably, this will be a tougher challenge for Phelps than that time he took on Shaquille O'Neal.
