Australian boxer Michael Katsidis has promised to go up a notch when he takes on Jesus `El Matador' Chavez in Austin, Texas on Sunday (AEDT) with a world title fight at stake.
The winner becomes mandatory contender to Mexico's WBO lightweight world champion Juan Manuel Marquez.
Queenslander Katsidis, 28, ranked No.2 by the WBO, needs a victory to re-establish his place among the major fighters in the talent-packed division.
The former WBO interim lightweight world champion has the perfect showcase to reignite his career in the US after suffering his only professional losses there last year to former world champions Juan Diaz and Joel Casamayor.
