According to Portal do Vale Tudo (via the UG), Antonio "Bigfoot" Silva will make his first appearance under the UFC banner against no other than the former Heavyweight champion Cain Velasquez.
The website credits Antonio Rodrigo Nogueira's interview to the Brazilian newspaper "Extra", where Minotauro reveals his new teammate Antonio Silva will make his first appearance inside the Octagon in April, against Cain Velasquez. None of the sides officially confirmed the news, but since Antonio Silva is now a part of Team Nogueira, Big Nog is more than just a reliable source in everything related to Bigfoot's Octagon debut.
Both Velasquez and Silva are coming off defeats in their most recent bouts. Silva was surprisingly TKO'd by Cain Velasquez's teammate Daniel Cormier last September, while Velasquez lost his title to Junior dos Santos via KO at UFC on FOX, which took place back in November.
My 2 Euro Cents:
Frank Mir was widely considered as the most logical choice for Cain Velasquez, who will look to prove a point after a disappointing performance against Junior dos Santos. Mir is currently one of the few Top 10 Heavyweights with a win-streak. In fact, the only fighters currently enjoying an unbeaten run inside the Octagon are Cheick Kongo, Travis Browne, and Mike Russow.
Velasquez vs. Mir is a perfect Heavyweight blockbuster, where both fighters have something to gain and something to lose. On the contrary, Cheick Kongo is currently the best option for Antonio "Bigfoot" Silva, who has to earn some credibility points by testing himself against a top Heavyweight striker.
