Saturday's featherweight title fight between challenger Juan Manuel Lopez and champion Orlando Salido figures to be a fight for survival. Less than a year ago, Salido (37-11-2, 25 KOs) scored a huge upset when he knocked out the heavily favored Lopez (31-1, 28 KOs) in the eighth round to capture the belt that again will be on the line, again in front of a Puerto Rican crowd that will watch the rematch at San Juan's Coliseo Roberto Clemente.
Salido, 31, proved that his victory was no lucky strike by making two solid defenses of his crown in his native Mexico in preparation for this clash. Puerto Rico's Lopez, 28, once the most feared man in this division, now faces the prospect of suffering a major career setback if he loses this challenge. The stage is set for a crossroads fight, after which the winner will have a chance to make a run at a series of high-profile fights in an interesting division while the other fighter sinks into fringe-contender territory.
Here are five keys to victory for Salido in this career-defining fight:
Act the part
Make it an inside job
Work the count
Eye of the tiger
Let the dogs out
