Ring walk music makes me think it's entirely possible Chisora had a joint in the dressing room before the fight...
With Lerena vs Dubois I think Lerena just made a huge mistake allowing Dubois to regroup. His coach probably underestimated how much of an explosive finisher Dubois is and told Lerena to pace himself. Instead he should have gone for broke as you could see in the 2nd Dubois was still hurt.
I think we're all only really watching for the after fight Confrontation between Fury and the cossack
I'm the best fighter on the planet bar none and if that was me in there against Fury I would be the third HW champion to post on this forum and FTR by far the best one
