If a sprinter is to beat Usain Bolt at his world championships farewell in August, it will likely be one of the men in the 100m field at the Diamond League opener in Doha on Friday.
Olympic silver and bronze medalists Justin Gatlin and Andre De Grasse headline the first of 14 meets in the Diamond League season that runs to Sept. 1.
Universal HD will air live coverage Friday from noon-2 p.m. ET, with NBC Sports Gold streaming the action.
Gatlin and De Grasse will each line up for an individual outdoors race for the first time since the Rio Olympics.
