The WBO champion at 154 pounds gets a tough test in the form of a late replacement opponent

In many cases, a late replacement opponent can remove intrigue from a pay-per-view main event. That is not the case on Saturday, when Sebastian Fundora steps in to challenge Tim Tszyu for his WBO junior middleweight title, as well as the vacant WBC belt. Tim Tszyu (c) -600 Sebastian Fundora +400 WBO and vacant WBC junior middleweight titles Isaac Cruz -300 Rolando Romero (c) +230 WBA junior welterweight title Julio Cesar Martinez (c) -375 Angelino Cordova +275 WBC flyweight title Erislandy Lara (c) -400 Michael Zerafa +300 WBA middleweight title Serhii Bohachuk Brian Mendoza Junior middleweight Elijah Garcia Kyrone Davis Middleweight

Fundora received the opportunity to step into the main event when former world champion Keith Thurman was forced out of his bout with Tszyu due to injury. It's no minor change in opponent, with the musclebound Thurman standing 5-foot-7 to Fundora's towering 6-foot-5.

This gives Fundora a fundamental advantage in fight preparation as he is always training to fight a shorter man while Tszyu now faces a man nearly a foot taller than the man he spent a training camp preparing for.
