Very hard to say, Vitali was leading on cards and was doing quite well, he had good pressure on Lewis but he got badly cut and it ended up here for legit reasons; Vitali was able still to continue fighting but the cut looked kinda serious to me. What would happened next? Would have Vitali won by decision? Would have he knocked out Lewis? Would Lewis have cut him even worst? It is an interesting question but we can only quite speculate about this one, personally I think that VItali is too talented and too iron chinned to have lost that one and I could imagine him banging Lewis down in the later rounds but this is only my opinion and I wouldn't argue with those disagreeing as we are left in the meta-speculation in a division where one punch can turn the tables on a whim.
