It wasn't scripted. It might as well have been an exhibition though as Jake was obviously taking it easy and Tyson probably just can't go full hog for more than a few minutes. Jake did throw a few huge punches that narrowly missed and it wouldn't have been pretty had they landed so I'm not sure he was pulling them all.
That's why we said it was scripted; Jake could have easily knocked him out before the second round, but he held back to entertain us for 9 rounds, making the entire fight appear tough. Tyson is older and unable to take as many punches as Jake.
Both players are banned for 24 days for the shit show
