"[Silva] said he won't fight him unless he gets PPV [points] so I guess he's gonna retire," White wrote via text message.
When asked what he plans on doing with Sonnen next, White wrote, "we will figure it out."
Silva wasn't available to comment on the situation.
The Sonnen-Silva feud has been brewing for two years ever since Silva posted a video of him confronting Sonnen about his comments about Brazil and his fellow Brazilian fighters on a media tour.
Sonnen called out Silva one more time moments after he submitted Shogun Rua at UFC Fight Night 26 last Saturday night in Boston.
