In the Jets/Dolphins game, Miami was punting and Nolan Caroll was running down the sideline covering the punt when a Jets staffer or inactive player stuck their knee out and tripped Carroll up. Carroll was down for a bit but this is the dirtiest play I've ever seen and I hope someone loses their job over it. Here is the link to Yahoo on the story and there is a video also. http://sports.yahoo.com/nfl/blog/shutdown_corner/post/Video-Jets-employee-trips-Dolphins-player-durin;_ylt=AlQe5gNnOI0k6c88tmcxe5o5nYcB?urn=nfl-294916
This has happened several times in the past and was the subject of a national story last year. I cannot imagine what the penalty would be? Maybe put the ball on the one yard line and kick the offender out of the league for a season.
