Earlier today news broke that Wanderlei Silva was out of his UFC 175 with Chael Sonnen and Vitor Belfort will replace him. Now more details have surfaced for the reason for changing the bout and things don't look good for Wanderlei Silva.
Wannderlei Silva was pulled from his scheduled UFC 175 grudge match against Chael Sonnen due to a failure to submit an application to fight in the state of Nevada, as well as his refusal to undergo a random drug test, sources told MMAFighting.com.
Silva had "ample time" to submit his application to compete at UFC 175 and elected not to do so, according to Nevada State Athletic Commission (NSAC) Executive Director Robert Bennett.
In addition, according to sources, both Silva and Sonnen were asked to undergo random drug tests while in Nevada last week for UFC 173. Sonnen complied with the request, however when asked to do the same, Silva refused.
NSAC officials declined to comment on matters regarding the random tests.
