By Dan Ambrose: According to fightnews.com, a fight between IBF/WBA light welterweight champion Lamont Peterson and Juan Manuel Marquez (53-6-1, 39 KO’s) is a possibility for the Cowboys stadium in Arlington, Texas at some point this year.

It’s unclear if the fight will take place next or at the end of the year. Marquez has been rumored to be facing former WBC lightweight champion David Diaz (36-4-1, 17 KO’s) in what would be a tune-up fight.

Why Marquez would need a tune-up against a fading lightweight like the 35-year-old Diaz is the real question. Marquez wants to move up in weight to 140lbs to possibly face Peterson, so it’s kind of confusing to understand facing a lightweight that is below the guys that Marquez has been facing for the most part.

Marquez would be better off skipping the Diaz fight and taking on one of the light welterweight fringe contenders before facing Peterson. But it’s still unknown if the Peterson-Marquez fight will come off and if so, if it will happen next.

You have to figure any fight that take place at the Cowboy stadium will involve Bob Arum promoting the fight along with a number of his Top Rank fighters.

Peterson recently beat IBF/WBA light welterweight champion Amir Khan to capture his two titles. Khan and his promotional team Golden Boy successfully appealed to the WBA and were granted an immediate rematch. Peterson hasn’t said whether he’ll fight Khan again or not. Peterson could end up getting stripped of the WBA belt by the World Boxing Association if he doesn’t fight Khan next. Khan doesn’t care about the IBF title, saying he’ll never fight for that belt again. He just wants the WBA title back. He may get it back but without an actual fight.

Marquez fought Manny Pacquiao in his last fight last November and lost by a 12 round majority decision. A lot of fans think Marquez won that fight, as do I. Pacquiao, not surprisingly, isn’t particularly interested in fighting Marquez right now. Hopefully he changes his mind before the end of the year, as Marquez said he won’t bother trying to fight Pacquiao again if he doesn’t fight him this year.
