In a classic man vs. beast race, Tennessee Titans running back Chris Johnson and Chicago Bears wide receiver Devin Hester tested their speed against the fastest being on the planet -- a cheetah -- for a segment on Nat Geo Wild, TheWrap.com reported.
Johnson and Hester ran against the fleet cat during a special Man vs. Cheetah show that will air this fall during the network's fourth Big Cat Week.
"This is most incredible challenge I've ever faced," Johnson said, according to TheWrap.com.
"I wanted to go up against the fastest in the world and test myself, and this was it!"
Johnson is considered one of the fastest players in the NFL after he ran a 4.24-second time in the 40-yard dash at the NFL Scouting Combine in 2008. Last season, Johnson rushed for 1,243 yards and averaged 4.5 yards per carry for the Titans.
The races hae been taped, but the results were not revealed. There was a barrier between the runners and the cheetah.
Hester, who has 12 punt returns for touchdowns during his career, said it was a unique challenge.
"But it was something I was ready to take on to see if I could get an edge on," Hester said.
Cheetahs have incredible acceleration and speed, going from 0 to 60 mph in three seconds and reaching top speeds of 70 mph in the wild.
The Nat Geo Wild network "loved the idea of a faceoff like no other between supreme athletes and an alpha predator," executive vice president and general manager Geoff Daniels said.
