Challenge Initiated By: Calgary
Type of Challenge: Off-Side
Result: Original call is overturned - No goal St. Louis
Explanation: Video review determined St. Louis's Ryan O'Reilly was off-side prior to David Perron's goal. According to Rule 38.9, "The standard for overturning the call in the event of a "GOAL" call on the ice is that the NHL Situation Room, after reviewing any and all available replays and consulting with the On-Ice Official(s), determines that one or more Players on the attacking team preceded the puck into the attacking zone prior to the goal being scored and that, as a result, the play should have been stopped for an 'Off-Side' infraction; where this standard is met, the goal will be disallowed."
The clock is reset to show 16:34 (3:26 elapsed time), when the off-side infraction occurred.
