San Jose Shark Dan Boyle took a bite out of his own team’s playoff run on Sunday night when he scored the only goal of their game against the Colorado Avalanche in overtime.

Trouble was, the goal went into his own net.

The 33-year-old defenseman from Ottawa was on the wrong end of a total fluke when he tried to clear the puck behind the net and instead shot it past his own goalie Evgeni Nabokov, giving the Avs a 1-0 win less than a minute into overtime after neither team scored in 60 minutes of regulation.

Here’s the play, followed by Boyle’s own words after the game, in which he called it “pretty much the worst thing that can happen.”
