LAUSANNE, Switzerland (AP) - Organizers of the Lausanne Diamond League meeting say American sprinter Justin Gatlin will miss the rest of the season due to an illness.

Gatlin, the 100-meter bronze medalist at the London Olympics, was slated to run in the Athletissima meet in Switzerland on Thursday.

Gatlin was treated for stomach pains and fever at a hospital in Austria this week.

Athletissima organizers say in a statement that "his situation has not improved." They say Gatlin "has taken the decision to return to the USA, withdrawing from the meeting in Lausanne as well as ending his season."

Gatlin was scheduled to face Olympic silver medalist Yohan Blake of Jamaica and American teammate Tyson Gay, who placed fourth in London.

Olympic champion Usain Bolt has opted to run the 200 on Thursday.
