Usain Bolt's anticipated season opener won't happen on Saturday at the Camperdown Classic, a low-key local meeting where the Jamaican sprint star had been expected to run. Since January Bolt's team had indicated he would participate in the meeting, for which his coach Glen Mills is meet director. On Friday, however, reports emerged that the 100m and 200m world record-holder would not run. Efforts to contact members of Bolt's management team were unsuccessful, however, a reliable source who asked not to be identified said Bolt left the island on Wednesday to seek treatment for a niggling injury. Bolt's training partner Yohan Blake, who won the 100m world title last year as Bolt false-started in the competition, was still expected to compete.
