Usain Bolt's management have moved to allay fitness concerns following his decision not to compete at this week's Jamaican National Senior Championships.
The six-time Olympic gold medallist, who has struggled for form this season, had been entered for the 100 metres, but his manager Ricky Simms said it had never been his definite intention to run.
Simms said in an email to Press Association Sport: "Usain was never confirmed to run at the trials. He put his name in to have the option."
Bolt qualifies for the 100m and 200m at August's World Championships automatically as the defending champion in both events, and is due to return to the track at the Diamond League meeting in Paris a week on Saturday before heading to Lausanne five days later.
Simms added: "I already told the media that Coach Mills [Bolt's coach Glen Mills] would make a decision on Wednesday if he needed the race or if he preferred him to train ahead of Paris and Lausanne."
Bolt, the 100m and 200m world record holder, has only managed best times of 10.12 seconds and 20.13secs over the two distances this year.
