The world's leading athletes will be keen to avoid any pre-publicity for the remainder of the world track and field championship in Daegu, South Korea.
On the first three days of competition athletes who have appeared on the cover of the official programme seem to have been jinxed.
Australia's Olympic and defending world pole vault champion Steve Hooker exited his competition on day one without making one clearance.
Day two's cover showcased the world's fastest man Usain Bolt who was promptly disqualified in the 100 metres final for a false start.
And yesterday Cuba's Olympic champion Dayron Robles, who at least got to the end of his race, was stripped of his 110 metres hurdles gold medal for obstructing the Chinese favourite Liu Xiang.
The two stars on today's programme are the Russian womens high jump champion Yelena
Isinbayeva, and Kenyan's middle distance track sensation David Rudisha.
