I believe this match was covered in one of those Arena Reports or whatever the Wrestler/Inside Wrestling called the (alleged) fan sent in match main event descriptions w/ the rest of the results listed below it and the head shots of the main eventers above it.
I remember very clearly that the report ended by saying Backlund looked uncomfortable with the decision or something like that, which fits the online match reviews.
The one match I remember being baffled by even as a mark was a report from Italy or something of a WWF show in 1987 being headlined by Volkoff vs Outback Jack.

I did love those things as sometimes the matches sounded awesome, such as when Don Muraco won a random house show battle royal after being left 2 on 1 vs Demolition, due to Jake the Snake tossing Damien on Demolition, leaving Muraco the opening to dump them.

In 1992 the Wrestler or Inside Wrestling had a photo spread from recent matches, and it included a battle royal that Tatanka lost, which left 10 year old Brody crestfallen as in my mind that meant the unbeaten streak was over.
