Wait, what happened? They were permitted to punt the kickoff?
Thanks to YoutubeTV's unlimited DVR, I have every NCAA/NFL football game recorded, so I just rewatched the sequence.
Missouri scored a touchdown. There was an unsportsmanlike conduct call on one of their Offensive Linemen on the play. Kansas elected to take the 15 yard penalty on the kickoff. So Missouri had to kick from their own 20 instead of the 35. Missouri sent their punter out there, ball in hand, and punted it like you would after a safety. And somehow, the refs (and everyone else) rolled with it.
Refs will miss bang-bang calls, penalties, etc. But this was one of those instances that simply can't occur in a low-level High School JV game, let alone a D1 game...and hence why the suspension was announced. It's inexcusable to mess that up.
