'Mitch Vogel broke a shoulder during the shooting.'
I remember reading in one those "movie mags" of the 60s how he broke it because some member of the production team played some sort of joke and spooked a horse (or the car ran amuck, something like that), and Mitch broke his shoulder.
You can bet *that* prankster was fired.
