In a release on Monday morning, the USATF announced its official roster of competitors heading to Beijing for the IAAF World Championships, set to take place from August 22-30.
Symmonds, who won his sixth 800m title at the US championships in June, has been vocal in recent weeks about Nike's requirements that US athletes, who may be sponsored by other shoe companies, wear Nike gear while at "official" team events.
On Saturday, Symmonds said in an interview that his problem with the Nike agreement is that the conditions on what is required of US athletes - as far as when and where they have to wear Nike gear - isn't clear.
Letsrun.com posted the full agreement that US athletes are required to sign, which says only that, "I will dress appropriately and respectfully for all 'official' Team functions, wearing the designated Team uniforms provided by USATF."
Symmonds is sponsored by Brooks Running, which is owned by Warren Buffett's Berkshire Hathaway.
Other major sponsors on the professional track circuit include Adidas, Saucony, Reebok, and Puma (which sponsors 100m world record holder Usain Bolt).
Word came down on Sunday night that Symmonds would not be on the team, and Symmonds said on Twitter that on Monday he'll "present proof that [the USATF] is stealing millions of dollars" from US track and field field athletes.
I just received word from @usatf that I have been left off the #Beijing2015 team.
