Gatlin speed impresses NFL coach

World and Olympic 100 metres champion Justin Gatlin has trained with NFL side Houston Texans as he waits for his drugs case to go to arbitration.

The American faces a ban of up to eight years after testing positive for testosterone at the Kansas Relays in April, his second failed drugs test, although the 24-year-old, who equalled Asafa Powell’s world record last season, is hopeful of being cleared.
