My guess would be that the Missouri fan was lipping off within earshot of Huston. This was the first time, in something like 25 years, that Nebraska lost to Missouri. I'm guessing that Huston was in no mood to be hearing smack from the Missouri fan, and clocked him. Justification? Hell, no! I'm
in Nebraska (though not really a Cornhusker fan) and I say suspend him (Huston). The "Big Red" has to many indescretions shoved under the carpet because these guys can do no wrong in the eyes of many Nebrasans. This little episode would have gone unnoticed and nothing made of it, except that it just happened to be caught by the camera for the enjoyment of all.
