2008 U.S. men's champion and two-time World bronze medalist Evan Lysacek announced on Thursday that he must withdraw from the World Figure Skating Championships to be held March 18-23 in Gothenburg, Sweden. Yesterday, Lysacek fell while practicing his triple axel and injured his left forearm, elbow and shoulder. There are no broken bones, but his doctors have advised him to rest for two weeks in order to maximize his recovery. Jeremy Abbott, who finished fourth at U.S. Nationals, will replace Lysacek, and will join Johnny Weir and Stephen Carriere in Sweden. In order for the U.S. to have three men's entrants at the 2009 Worlds (in Los Angeles), the placements of two of the men for 2008 Worlds must add up to 13 points or fewer. So for example, Weir can place 5th and Carriere can place 8th (5+8=13), or Carriere can place 3rd and Abbott can place 10th (3+10=13), you get the idea...Lysacek's news comes on the heels of another withdrawal earlier this week, that of European ice dance champions Oksana Domnina and Maxim Shabalin. They were one of the favorites to win their event, but will miss Worlds after Shabalin re-injured his left knee.
