Yeah, I suspect that is what it was, but it was just sooo phony and telegraphed.
It was a fight that occurred a few years ago on whatever MMA deal Showtime had going, I think Strikeforce.
Let’s see, you might be thinking of his adopted brother FRANK Shamrock. Ken never fought in Strikeforce.
Frank’s last fight was in Strikeforce in ‘09 against Nick Diaz.

That must be it, he does it during the final minute of round 1.
