DETROIT?(UPDATE) Timothy Bradley and Devon Alexander will try to breathe some life back into American boxing when the two undefeated 140-pound champions fight for the world title Saturday at the Silverdome arena.

And the winner is hoping to get a fight with either Filipino boxing superstar Manny Pacquiao or American Floyd Mayweather.

"I do think the state of boxing right now is at a low," Bradley said. "Until you have great fights like this in the 140 division. We are the most talented division in boxing, and we are going to bring it back just like the old days."

In the past few years, mixed martial arts has made a dent in boxing's revenue in the United States as the ticket-buying public has expressed displeasure in the sport's hodgepodge of sanctioning bodies.

Bradley (26-0, 11 knockouts) of Palm Spring, California, is the World Boxing Organization 140-pound champion and St. Louis southpaw Alexander (21-0, 13 KOs) is the World Boxing Council's champ.
