PARIS -- American sprinters Tyson Gay and Justin Gatlin will compete at the French stage of the Diamond League meet July 6.
Organizers say world-record holder Usain Bolt will miss the Areva meet in Paris.
Gay returned to competition last week after undergoing hip surgery in July 2011, running the 100 meters in 10.0 seconds at the adidas Grand Prix. He will race in the U.S. Olympic trials this month.
To make the U.S. squad for the London Games, he has to finish in the top three at the trials.
Four Americans, including Gatlin, a former Olympic gold medalist, already have broken the 10-second barrier this season.
Bolt returned to Jamaica for its national trials after beating Asafa Powell by 0.06 seconds at the Oslo meet last week.
