Sounds like the 1989 Thanksgiving Day affair at Texas Stadium. Eagles won 27-0 and it wasn't that close. If memory serves, Britt Hager went after Troy Aikman and that's when the brouhaha ensued out of the endzone.
That game was also the infamous Bounty Bowl with Buddy Ryan and poor little Luis Zendejas.
I could be wrong, but that sounds like the one you're talking about.
