As a general rule, the position of the ball in relation to the goal line is always reviewable by instant replay.
ARTICLE 6.Situations that may be addressed by the replay official:
c. With less than one minute in either half and a replay review results in the on-field ruling being overturned, and the correct ruling would not have stopped the game clock, then the clock will be reset to the time the ball is declared dead by replay. The referee will subtract 10 seconds from the game clock and the game clock will start on the referee’s signal. Either team may use a team timeout to avoid the runoff.
