Guerrero is from Gilroy and he's been working his way up the ranks for years. As a 10-to-1 underdog, this is his chance to shock the world.
The man known as "The Ghost" knows that upsetting Floyd is going to be a challenge.
"You know you have to be ready to do everything with Floyd. People say you need an A to C game plan. With Floyd, you need an A to Z game plan," he said.
"You have to be ready for whatever because Floyd's the type of guy where he makes adjustments here and there, and makes it tough for fighters to get in there with him. Throughout my career, everybody's seen I've been able to make adjustments in the ring," he continued.
