Usain Bolt has pulled out of the Weltklasse Diamond League meeting in Zurich on Thursday, organisers have announced.
The Jamaican, who clocked 9.98 seconds in Warsaw on Saturday night in only his second individual race of an injury-hampered season, has opted to bring an early end to his campaign. Zurich had been his last scheduled competition.
A statement from organisers said Bolt's coach Glen Mills was satisfied with his performances on his comeback from the foot injury which had delayed his start to the season, but "feels it is now time to shut it down while he is healthy and injury free with a view on his preparations for the 2015 season".
The six-time Olympic champion, who will resume training in October, will be looking to retain his world 100m and 200m crowns at the World Championships in Beijing next year.
The world's fastest man has competed only four times this year, twice at the Commonwealth Games in Glasgow as he anchored Jamaica to 4x100m relay gold, on the Copacabana beach in Rio de Janeiro in the Mano a Mano race where he won in 10.06secs and then in Warsaw, where he his time was an unofficial world best for an indoor 100m.
Bolt had been due to take on Great Britain's European champions James Dasaolu and Adam Gemili in Zurich.
Patrick Magyar, the Weltklasse meeting director, said: "Usain's body has delivered tremendous performances over the last years.
But, it is a body and not a machine. If an athlete of that level and his coach feel more rest is needed, we are certainly not going to question this and fully support this decision."
