Khan has been growing and maturing as a young man. He was still a boy when he turned pro and has naturally got bigger. If he was draining himself to make 135 then going up in weight would be beneficial for him and would actually make him stronger.

Should we label every boxer who ever goes up in weight as a possible cheat? I actually think blood testing in boxing should be the norm not the exception and I actually applaud Mayweather for bringing it up and making it an issue. It's something the boxing organisations need to look into to make this sport safer and rid it of its cheats. If Manny is cheating then you can be sure he isn't the only one doing it. Especially if it's "that easy" to go undetected.

So why not as of today have random blood testing for every fight. Perhaps with the last test being 20 days before the fight and then one straight after the fight. If you refuse the test you don't fight. That would make it a clean and fair sport.
