From season 2 of Burke's Law (1st series):
A pro wrestler is killed while in the ring during a title fight. The job for Captain Amos Burke (Gene Barry), of course, is to find the killer.
With guest stars Annette Funicello (ex-The Mickey Mouse Club), cast against type, as is her beach movie partner, Frankie Avalon, and Robert Middleton.
I wish I had some idea who the wrestlers were in this episode, but they were not given screen credit. And it's obvious one of them might've been a stunt double for Barry in the climatic fight scene.
