Gus Frerotte injuring his neck on a celebration play.. I have been searching far and wide for it.

No, but I remember the headbutt.
Wasn't that the tie game where Hostetler (in relief of the injured Frerotte) kept dropping the ball, and Westbrook took his helmet off on the field right at the end?
I don't know where you'd find a stand-alone video of that "celebration"...but really, you're not missing anything. Find a more positive clip to watch.

Try searching using the keywords "bonehead play" instead of celebration play....or bonehead celebrations.
