Kambasos may hurt Haney but could not KO him for sure.
In that case we gonna expect the fight to last long or to reach up to the officials decisions and it would be nice if one of them will dominate the others and somehow a way find to beat his opponent by knockout because that would be best thing to conclude the match and to win the fight.
There's a very high chance that this fight will go for 12 rounds rather than seeing a KO, I'm not saying that there's no chance for both boxers to have a KO win but both of them have almost the same record and capabilities. A 5.5% difference in KO history is not that much but as I said, a chance is a chance but it's really slim, IMO. We might see a consecutive exchanging of blows because both of them have a point to prove.
