A cold is never good it can be a virus which can make the person tired, and then they have an excuse later. Sometimes I worry fighter will get a bad cold and cancel the fight. Colds are common as they say.
What people don't understand is that constant exercise is horrible for the body and will weaken the immune system. So yes it's possible that Wilder has a cold like he did for Ortiz and has been overtraining. Either way if true then he's going to have a big problem tonight. He voiced it because he'll have an excuse if he loses and a better reputation if he beats Fury because he did it while sick.
He might have had a cold in both this and the Ortiz fight. With the exhausting training schedule, plus the stress of media and constant travel, its totally plausible that the guy would be more suseptible to getting sick. In combat sports injuries and illnesses have a knack for appearing at the worst possible time. What's really more significant is the fact that Wilder is openly talking about the illness. I can't really see any upside to discussing it publicly.
A cold didn’t stop Joshua from flattening Povetkin but let’s get that excuse in early for the Wilder fanboys. He’s already fighting an inactive, mentally unstable drug addict, how many more excuses?
