"Unfortunately had to notify @usatf that @AjeeW will not be able to represent Team USA at @iaaf Beijing #injury she even had during US Champs." the athletes manager Ray Flynn tweeted.
Prior to world championships Wilson was mentioned as possible medal contender for this month's world championships.
Wilson's season best mark of 1:57.87 in 800m is the third fastest in the world in 2015. Only defending world champion Eunice Sum of Kenya 1:56.99 and Cuba's Rose Almanza 1:57.70 have run faster than Wilson.
Molly Ludlow, who finished fourth at the U.S. trials, will replace Wilson.
