Russia's tennis champion Maria Sharapova is seen during a press conference in Dubai during which she announced on February 26, 2008 her withdrawal from the WTA Dubai Tennis Championships due to a viral illness. Sharapova hopes to rival world number one Justine Henin this year despite deciding to withdraw from the Dubai Open on the second day of the tournament because of a virus, she said. The Australian Open champion played all the way through the Doha tournament with the same virus, she claims, and felt worse when she woke up in Dubai yesterday.
