Boxing superstars Duran, Chavez, Barrera spotted at ringside for Pacquiao-Bradley III
Marco Antonio Barrera is around to see former rival Manny Pacquiao see action again.

LAS VEGAS — The third fight between Manny Pacquiao and Tim Bradley is not lacking in star power.

Boxing greats Roberto Duran and Julio Cesar Chavez were among those spotted at ringside of the MGM Grand to watch the Pacquiao-Bradley showdown, which could possibly be the final fight of the 37-year-old Pacquiao.

Legendary Mexican fighters Marco Antonio Barrera and Juan Manuel Marquez were also around for the fight on this wet and rainy Saturday night (Sunday, Manila time) by the desert.

Both Barrera and Marquez fought Pacquiao more than once in the past decade. Only Marquez was succesful in dealing the Filipino a loss during that stretch, scoring a stunning sixth round knockout in 2012.
