UFC heavyweight Antonio “Bigfoot” Silva issued a challenge via Twitter late Saturday night after watching Thiago Silva defeat Rafael Cavalcante at UFC on FUEL TV 10.

Bigfoot, it would appear, as a “debt to settle” with the light heavyweight, and wants him to com up to heavyweight and meet him.

“He must be sad because I left American Top Team,” Silva said Saturday night. “If he wants to fight me, he has to come down to 205. That’s it.”

Antonio Silva stated that Thiago Silva “weights 105 kilograms (231 pounds)” on Twitter, making it an easy decision for him to face him at the bigger division. Silva is coming off a loss to UFC heavyweight champion Cain Velasquez.
