Tampa Bay Lightning head coach Jon Cooper was none too pleased after his team had a goal wiped out by a Coach’s Challenge.

Barclay Goodrow scored just moments after Boston’s Nick Ritchie opened the scoring in Tuesday’s Game 1.  Bruins head coach Bruce Cassidy challenged the play for offside.

After a quick discussion between linesmen Steve Barton and Devin Berg and the NHL’s Situation Room, the goal was overturned.

Tampa forward Brayden Point, skating casually toward the bench, failed to reach the blue line on the delayed offside before Goodrow entered the zone. From Rule 83.3:

A situation where an attacking player (or players) has preceded the puck across the attacking blue line, but the defending team is in a position to bring the puck back out of its defending zone without any delay or contact with an attacking player, or, the attacking players are in the process of clearing the attacking zone.

If an off-side call is delayed, the Linesman shall drop his arm to nullify the off-side violation and allow play to continue if: (i) All players of the offending team clear the zone at the same instant (skate contact with the blue line) permitting the attacking players to re-enter the attacking zone, or (ii) The defending team passes or carries the puck into the neutral zone.

Point failed to properly tag up.

Lightning coach Jon Cooper was furious.  Not with his winger, though. Coop was angry with the officials.

“You [*******] guessed!” Cooper appeared to be yelling from the bench.

Nobody guessed, but – to be fair – the call was close enough to require video review.  Ultimately, Point was offside.

Here’s the official word from the NHL:

It was determined that Tampa Bay’s Brayden Point did not legally tag up at the blue line prior to Barclay Goodrow entering the offensive zone.

Clock is reset to show 14:56 (5:04 elapsed time), when the off-side infraction occurred.

Tampa went on to win the game 5-4 in overtime.
