Rios on Cotto-Margarito II undercard

Unbeaten WBA lightweight titleholder Brandon Rios, of Oxnard, Calif., has been added to the undercard of the rematch between WBA junior middleweight titleholder Miguel Cotto and Antonio Margarito, Top Rank Inc. Promoter Bob Arum told RingTV.com on Sunday.

The 25-year-old Rios (28-0-1, 21 KOs) will be after his 11th win in a row, his 10th consecutive knockout during that run and his fourth straight stoppage against an opponent to be determined. The fight will be televised on HBO Pay Per View from New York's Madison Square Garden.

Rios and Margarito are both trained by Robert Garcia.

"This is great, because I get to fight in the same place and on the same card where my buddy, Antonio, is fighting at. My boy Margarito is going to be fighting on there, so that's going to make it easier for Robert. We'll both be in the same gym training for the same day, so it's great," said Rios, who was originally scheduled to fight on Dec. 10.

"Like I said, this is going to be great being my first time fighting there. Now everybody who is on the East Coast is going to know who I am. All of the people in New York are going to see who I am, and they're going to see a great performance on my behalf."
