Calzaghe will hurt his hand a few rounds in anyways. It will be even territory if its true! If it is hurt just stick a couple injections in the hand before the fight and it'll be ok. This will not be a problem even if it's true.

But I never believe these "facts" that come out before a fight. Could be a psych out, could be false, could be a little pre-excuse to fall back on. Lots of motives.
