Good fight. I could see Dubois getting hurt and knocked down but eventually getting the knockout over a gassed Tommy Morrison in the mid rounds.
Dubois was nearly stopped in the first round by Lerena, was getting outboxed by Hrgovic until he gassed, and has been kayoed twice by jabs. I don't think Morrison has "no chance."
I think it would have been a slugfest with several knockdowns, both powerful fighters but pierceable in defense. I think the Englishman's better chin could have been decisive and I say Dubois by tko before the 10th round.
Have a look at the Lerana fight and consider whether or not Tommy would have finished the job. I certainly think he does
