You cannot gouge an eye with it but you can do enough damage if intended. Just watch Cunningham-Ross video.
That didn't look like a thumb at all. WTF ya'll talkin about? You know how much it would hurt Lewis' thumb if that was the scenario? That's implying that the thumb hit and made Vitali's head whip back which is ****in ridiculous. It was obviously the far left knuckles that connected and it's doubtful the thumb even made contact at all.
lol this is why we all hate the Klit huggers. Your boy got whupped and was starting to hug at every oppotunity. Lewis would of stopped him in the next few rounds.
Lewis used his head, his corncrows and now , just now, yes right this minute you have revealed that he thumbed his eyes out startling revelation, how come no one else picked it up >?
