The San Jose Sharks are playing for their lives tonight as they play the Blues in St. Louis in Game 6 of the Western Conference Finals. 

The Blues are up 3-2 in the series and have won two games in a row with momentum on their side. 

San Jose received some bad news this morning and really doesn't help the chances of the Sharks staying alive. 

The Sharks announced that Erik Karlsson and Tomas Hertl won't be playing tonight as they didn't even make the trip to St. Louis. 

Joe Pavelski will be a game time decision and didn't skate during practice. 

This lines up for the perfect opportunity for the Blues to close the door and book their trip to the Stanley Cup Finals.
