Brandon Rios knows that his upcoming title fight with Miguel Acosta won't be easy. One of the reasons why he is confident that will leave the ring with his hand raised is because of the sparring he received in training camp.

Rios' sparring partners ranged from lightweights to middleweights. One of the fighters that Rios sparred with is Victor Cayo (26-1) out of the Dominican Republic. The junior welterweight's only defeat was a TKO loss to the heavy handed Marcos Maidana last March.

Rios feels that Cayo's style is very similar to the style of Acosta. Rios told BoxingScene, "I sparred a lot with Victor Cayo. Cayo was the perfect sparring partner because of his style.  If you have seen a Cayo fight then you have seen an Acosta fight."

Acosta-Rios takes place on Saturday at The Palms in Las Vegas and will be broadcast by Showtime on Saturday.
