A sub-10-second time in the 100 meters on Saturday suggested that Usain Bolt's injury-plagued season might be rounding into form.
The Jamaican sprinter has withdrawn from an upcoming IAAF Diamond League meet in Zurich and announced that he will forgo any more competition in 2014.
“Usain’s body has delivered tremendous performances over the last years. But it is a body and not a machine," said Patrick Magyar, the meet's director. "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.”
Battling a foot injury, Bolt had competed in only a relay at the Commonwealth Games and a Rio de Janeiro exhibition this season before this past weekend.
His coach, Glen Mills, wants the world's fastest human to "shut it down" for a few months, Magyar said. Mills said that Bolt is healthy in the wake of a 9.98-second time in Warsaw on Saturday.
