re: Clock and Helmet issue at the end of the first half

The personal foul was against a TCU player that had stayed on the field. He got into a shoving/shouting match with a few LSU players and then said something in front of the referee. The referee immediately through a flag. I was at the game and it happened near my side of the field and seats, but I obviously couldn't hear what was said. The referee clearly announced the dead ball unsportsmanlike conduct penalty against the TCU player and if you watch the replay, you can see the TCU player arguing his case after the penalty was called.
