BoxingScene.com was advised that undefeated featherweight contender Mikey Garcia (23-0, 19KOs) will likely replace Brandon Rios on the televised portion of Top Rank's scheduled pay-per-view on December 4 at the Honda Center in Anaheim, California. The main event will feature Julio Cesar Chavez Jr. vs. Alfonso Gomez.

Rios was pulled off the show by Top Rank in order to replace the injured Kelly Pavlik, who withdrew on Monday from his scheduled fight on the Manny Pacquiao-Antonio Margarito pay-per-view undercard, which takes place on November 13 at Cowboys Stadium in Texas.

The original plan was to have Vanes Martiroysan replace Rios, but BoxingScene has learned that the unbeaten Armenian doesn't have enough time to get ready for a fight on December 4. Vanes has spent very little time with his trainer, Freddie Roach, who is currently training both Pacquiao and Amir Khan for their upcoming fights. Additionally, Vanes is pushing for a fight with WBO champion Sergei Dzinziruk.

A final decision should be made in the next few days.
