On a play at the end of the fourth quarter as time was running out with the ball on the defense 5 yard the runner tries to dive into the end zone but is stopped under a pile of defenders within a foot of the goal line.
The officials signaled to stop the clock to determine forward progress and to clear the pile of players to set the ball. When the ball was set the official wound his arm to start the clock again.
Was it correct to stop the clock in this situation to determine the progress to the goal line as well as to set the ball?
thanks.
