2/11/2010 - Boxing

The televised undercard bouts for the March 13 welterweight title fight between Manny Pacquiao and Joshua Clottey at Cowboys Stadium were finalized Thursday.

WBC super featherweight champion Humberto Soto will fight former WBC lightweight champion David Diaz for the vacant WBC lightweight title.

A pair of 10 round bouts featuring former two-time world champion Jose Castillo and popular middleweight John Duddy will also take place.

Castillo will fight Alfonso Gomez and Duddy takes on Michael Medina, in a pair of middleweight bouts.

Also, promoter Bob Arum said the nephew of Hall of Famer Salvador Sanchez, Salvador Sanchez III, and undefeated Dallas boxer Roberto Marroquin will fight in separate non-televised undercard bouts.

"Each matchup will feature a world class fighter from a different region of Mexico or a Hispanic region in the United States," Arum said.
