Chael Sonnen Raises The Stakes In Calling Out Silva

With two recent title fights in his rear view mirror, Chael Sonnen has a spot open on his dance card, and it is looking like he wants to fill it with former Pride light heavyweight champion Wanderlei Silva. Sonnen has already called him out on UFC Tonight and asked him to fight at the first FOX Sports card, but it seems now Sonnen has raised the stakes. According to a tweet from Sonnen, he will donate ten percent of his purse to charity if Silva accepts within twenty four hours.

Sonnen via twitter:

Wand- you have 24 hours to accept. If you do, I will donate 10% of my purse to help schools in your hometown of Curitiba .. I mean, VEGAS.
