The San Jose Sharks are playing against the hometown St. Louis Blues in the second game of their opening-round 2012 NHL playoff series. Through the first period of play, the Sharks are trailing 1-0 ... but the Blues goal was not the direct result of the Blues offense.

At 1:31 of the first period, Marc-Edouard Vlasic was attempting to clear a puck that got through the legs of Sharks goalkeeper Antti Niemi, but ended up knocking it into the net, scoring a Sharks own goal ... one that was credited to Blues skater Vladimir Sobotka (unassisted).

There was no further scoring for the rest of the period, but the Sharks will need to recover from that unfortunate gaffe.
