Gay misses Palace showdown

American sprinter Tyson Gay has pulled out of his head-to-head with Asafa Powell at Crystal Palace tomorrow, amid fears over his fitness just three weeks before the Olympics. Gay, world 100m and 200m champion, damaged a hamstring earlier this month, but was expected to line up against Jamaican Powell tomorrow. Powell, for his part, was looking forward to the race with confidence after beating world record holder Usain Bolt in Stockholm on Tuesday."The American withdrew from the Aviva London Grand Prix and, while that is a massive blow for the organisers, the fear is that he will be undercooked for next month’s Games in Beijing," writes Rick Broadbent in the Times.
