Of course not, because it never happened. Even those mock-up trailers and far-fetched story lines for Rocky 6 (that became the spectacular Rocky Balboa) couldn’t have predicted that.
The good folks at Budweiser did though for their Superbowl ad that, as a non-US, I had to find online instead of at half time (just like the Bruce gig too):
As both a fan of the Rocky series (I’ll even watch number 5 occasionally) and Budweiser’s adverts, this makes me laugh each time.
To me it reeks of Rocky 4, the back-to-basics approach of training in a stable in Russia. Equestrian workout: the best way to train for boxing? Some of those saddles can be pretty heavy I guess.
