Speedy Chris Johnson tests himself racing cheetah, now ready to run Titans back to playoffs

Chris Johnson refuses to spoil the ending, so everyone will just have to tune in come November to see how he fared against a cheetah.

The Titans running back and Chicago receiver Devin Hester took part in the human versus animal race for a cable TV special.

While most people don't give Hester or Johnson much of chance against a cheetah, Johnson says he ran at full speed.

A year ago, some didn't give Johnson a chance against defenses; he was repeatedly questioned whether he had lost a step, or more. He responded by scoring three touchdowns of 80 yards or longer, giving him six in his career.

Now Johnson enters his sixth season with a new position coach and trying to once again run the Titans to the playoffs.
