Jorge "Golden Boy" Linares (42-3, 27 KO'S), the WBC Diamond Champion and WBA lightweight champion, fights British challenger Luke Campbell (17-1, 14 KO'S) this Saturday, at the Los Angeles Forum, California, and it'll be broadcast live on HBO.

Linares, a triple division champion from Barinas, Venezuela, has fought in   Japan and the UK. However, he'll be fighting in the United States for the first time in three years,  and just a mere six months following  his second victory over Brit  Anthony "Million Dollar" Crolla in his hometown of Manchester, England.

Campbell, a former WBC Silver lightweight champion and gold medal winner at the 2012 London Olympics, has defeated five strong contenders, including Darleys Perez, Derry Matthews, and Argenis Méndez.

Linares, showing his great physical condition and commitment, tipped 137 pounds, seven days before the fight.

Linares, 32, is a three-division champion, having also won featherweight and super featherweight titles. Returning to the U.S. after a three-year stretch fighting abroad, he’s on an 11-bout win streak and making the second defense of his lightweight crown.

With only one blemish on his professional record, Campbell, 29, has steadily risen in the rankings and is making his first bid for a title in his U.S. debut. Turning pro in 2013, Campbell has fought his entire career to date in Great Britain.

The opening bout pits San Diego’s undefeated Antonio Orozco (26-0, 17 KOs) against ring veteran Roberto Ortiz (35-1-2, 26 KOs) from Torreón, Mexico in a scheduled ten-round super lightweight contest.

Orozco, 29, is a rising star in the 140-pound division thanks to speed and counter-punching. With one controversial loss, Ortiz, 31, will rely on his experience and punching power.
