<p>Jamaica’s 4x100 metres relay team has suffered a setback after tests showed former world record holder Asafa Powell has a minor muscle tear that will probably keep him out of the race, his manager told Reuters on Monday. <br /><br /></p>.<p>“An ultrasound showed he has a minor tear in his adductor muscle,” Paul Doyle said. “It is very unlikely he will be ready to go in the relay in a few days.” <br /><br />Powell anchored the Jamaicans to a world record in the relay at the 2008 Beijing Olympics. But he was missing through injury when a team of Nesta Carter, Michael Frater, Yohan Blake and Usain Bolt lowered the record to 37.04 seconds at last year’s world championships in South Korea. <br /><br />All four are in London as part of Jamaica’s relay squad. Powell, the former 100 metres world record holder, finished last in Sunday’s 100 metres final when he pulled a groin muscle in the last 50 metres as Bolt and Blake sped to gold and silver. <br /><br />He is scheduled to have additional medical tests later on Monday. Doyle denied Powell had already scheduled season-ending surgery to correct the groin problem.</p>
