As expected, Tyson Gay has been left off the U.S. roster for next month's world championships in Moscow.
Gay qualified in the 100 and 200 meters at the nationals in June, but relinquished his spots after failing an out-of-competition drug test for a banned substance. Mike Rodgers will take Gay's place in the 100 and Wallace Spearmon will go in the 200.
The team was announced Monday by USA Track and Field.
Carmelita Jeter will run the 100 and will be among several Americans trying to defend their world titles beginning Aug. 10. The U.S. team also includes up-and-comers such as 17-year-old Mary Cain in the 1,500.
Finally healthy this season, Gay was expected to push Usain Bolt at the worlds. But instead of racing in Russia, Gay will be trying to resolve his doping case.
