Tennessee Titans running back Chris Johnson is the sixth NFL player to rush for more than 2,000 yards.

But how would he fare on a running track, without a helmet and pads, against the world’s fastest man?

We just might find out.

Sources close to the situation told ESPN NFL Insider Adam Schefter that representatives for the Titans running back and Olympic champion Usain Bolt of Jamaica have spent recent days trying to set up a race between the two men to determine who really is the world’s fastest human.

The race would be used to raise money for charity.

Bolt won three gold medals at the 2008 Summer Olympics in Beijing, setting world records in the 100 meters and 200 meters and sharing a third world record with the Jamaican 4×100 meter relay team. At last year’s world championships, he shattered both of his own sprinting records, running the 100 meters in 9.58 seconds and the 200 meters in 19.19 seconds.

Johnson on Sunday became the NFL’s sixth 2,000-yard rusher when he completed his season with 2,006, breaking Earl Campbell’s franchise record of 1,934. The second-year back from East Carolina also broke Marshall Faulk’s NFL single-season record with 2,254 total yards from scrimmage.

At the 2008 NFL scouting combine, Johnson was timed in the 40-yard dash at 4.24 seconds — the fastest time clocked at the combine that year.

According to sources, the one hangup seems to be the length of the race. Johnson wants the race to be 60 yards or less, while Bolt would like it to be longer.

Johnson’s longest run from scrimmage this season was a 91-yard touchdown run in Week 2.
