Harrison wouldn't have got clearance to fight with an abscess in his mouth, there nasty, especially when in a bout, ur gonna get punched in the mouth!!
Harrison won't back down from anyone, just a shame he's got Warren as his promoter. Calzaghe has pulled out of quite a few fights, the Johnson one twice and the Lacy one got put back, so don't jump the gun and call Harrison unprofessional. Stuff like this happens all the time in boxing. It's just part and parcel of the business!
