LSU/Arkansas Clock Situation

[Fan10]

Can anyone explain this clock situation? With 1:40 to go on a play where the ball carrier was tackled inbounds, Arkansas had an injured player. After he was helped off, the clock started on the snap. You could see Bobby Petrino saying, "That's bull ----," and based on what I saw, quite frankly, I agree. Did I miss something that would have caused it to start on the snap? It wound up not mattering because LSU fumbled on the ensuing possession, but it could have given LSU 25 extra seconds.

I thought that the play-clock should have been set to 25 seconds and the clock started on the referees signal. The only adjustment from a normal down is that the offense doesn't get the entire 40 seconds. If it had been a defensive player the play clock would be set at 40 and the game clock would start on the referee's signal. There are situations in which the referee could hold the game clock until the snap but this shouldn't have been one of them.

The referee can enforce 3-4-3 if he feels either team is conserving or consuming time by tactics that are unfair. If he felt the injured player was trying to do so in a way to conserve time, he could start it on the snap. I did not see the play and I'm not saying he should have but he can.

I was watching this game live and on the phone with my family in Little Rock as it happened. Not only could you read Petrino's lips, you could hear it over the audio. With no other information, the 3-4-3 decision seems logical, and would explain why Petrino got so hot--it's a judgment call.
Through most of that games I watched yesterday, the TV crews did a good job of getting details regarding the rulings and the replay analysis to the broadcast booth so it could be stated on air. It's made watching the game much more enjoyable.

Who had the ball, where, and what was the score when this happened?

Ball was on LSU's 48. The player was slow to get up and the ref stopped the clock. He, then, got up and limped across the field to his sideline without any assistance or trainers coming out to the field. Arkansas had the ball.

I am not sure if he was delaying but had been slow to get up on a few previous plays and remained in the game. I can see why the judgement would be exercised there because this one was longer than before.
