Expect Floyd Mayweather and Marcos Maidana to weigh in under the welterweight limit on Friday. Both are ultimate professionals who wouldn't risk severe financial penalties by coming in over weight. Both will come in close to the 147 welterweight limit and Floyd Mayweather might come in a couple of pounds under, as he normally does.
Unofficial scales showed Maidana had a 17 pound advantage in fighting weight, before entering the ring in the first fight. This weight difference is substantial and Mayweather can make this extra weight count by fighting on the inside and holding as much as possible.
This should be an interesting fight and is definitely worthy of the mega fight status that it is current achieving.
