The Coyotes were on the wrong side of a controversial non-call in the final minute of regulation Sunday afternoon. The Vegas Golden Knights capitalized to score the game's lone goal with 42 seconds remaining.
The 1-0 loss was the Coyotes' first in regulation at home.
Vegas' Alex Tuch dumped the puck into the Coyotes' zone from the Golden Knights' side of the red line. Jakob Chychrun was the first player to the hash marks, anticipating an icing call, which would have granted the Coyotes an offensive zone face-off.
Golden Knight Jonathan Marchessault retrieved the puck and passed to William Karlsson, who scored from the slot.
"It's a human error," head coach Rick Tocchet said. "(The linesman) is an experienced linesman. It's one of those … I can't speak for him. He's a good guy. He's a good linesman. Unfortunately, he made the mistake. I understand.
"But we've got to play to the whistle. I understand people think it was icing, but you've got to understand the antennas have to be up with 40 seconds (remaining). You can't leave human error for chance."
