===={{anchor|Instant replay review challenges}} Review challenges====
Beginning in the [[2015–16 NHL season]], instant replay reviews have been expanded to include a coach's challenge. Each coach receives one challenge per game, for which only the goaltender interference challenge requires the use of a timeout. Coaches may only challenge over situations whether the goal should have been disallowed because of goaltender interference, a missed stoppage during play, or an offside, or whether a goal disallowed because of goaltender interference should be allowed instead. The challenging team retains its timeout and its challenge after every overturned goaltender interference call. There are two situations that happen when a challenge is upheld:
*If an offside review or missed stoppage review is upheld, the challenging team receives a minor penalty for delay of game.
*If a goaltender interference review is upheld, the challenging team loses its timeout.

Challenges are not allowed during the final minute of regulation, as well as at any point during overtime. In this situation, officials in the Situation Room reviews all instances where the puck entered the net, and then determines the final ruling. However, for reviews that take place during coach's challenges, the on-ice officials determine the final ruling.
