BERLIN (AP) - 2008 Olympic women's pole vault silver medalist Jenn Stuczynski will not compete at the 2009 IAAF World Championships in Athletics due to an injury. The Championships will take place August 15-23 at the 1936 Olympic Stadium in Berlin.

The #2 women's pole vaulter of all time and a four-time USA Outdoor champion, Stuczynski has been battling a nagging injury of late that will keep her from competing at the World Championships.

"Despite my focused efforts for the last five weeks to get 100% healthy, I made the decision on Sunday that I just can't be ready in time to compete in Berlin," said Stuczynski. "The doctors who are treating me say that my Achilles injury is not serious, but it just has not improved enough for me to vault next weekend. I think I just ran out of time. I'm disappointed I won't get the opportunity to join Team USA in Germany."

Stuczynski will be replaced on the Team USA roster by 2004 Olympian and three-time previous U.S. World Outdoor Championships team member Jillian Schwartz.
