San Jose Sharks defenceman Erik Karlsson missed Wednesday's season-opener to attend to a personal matter, the team announced on Twitter.

The team did not give a specific reason for his absence or suggest when he may be back on the ice. After the game, head coach Peter DeBoer said the team did not have an update on the two-time Norris Trophy winner. 

The Sharks began the season against the Vegas Golden Knights with a 4-1 loss at T-Mobile Arena to kick off the 2019-20 campaign. They will then host the Knights in their home-opener on Friday night.
