The reigning Olympic sprint champion Usain Bolt will have to qualify for the 100 metres at this year's world championships.
Jamaican athletics officials have decided the country's automatic entry into the race should go to his training partner Yohan Blake, who is the reigning champion having won the title in 2011.
Bolt was disqualified from that race two years ago when he false started.
He will now have to qualify to gain Jamaica's wildcard.
Bolt has however gained automatic entry for the 200 metres, as he's the reigning world champion.
