Erik Karlsson was not at Sharks practice Thursday morning after missing Wednesday night’s season-opening loss in Las Vegas.

“I can’t share anything and I don’t know,” Sharks coach Pete DeBoer told reporters when asked about Karlsson’s status for Friday night’s home opener, a return date with the Vegas Golden Knights.

Karlsson’s absence was announced just before warmups of the Vegas game, a 4-1 Golden Knights victory. The Sharks have only said Karlsson is tending to a personal matter.

Back at practice Thursday were Timo Meier and Kevin Labanc, both of whom left Wednesday night’s game at T-Mobile Arena with apparent injuries.

DeBoer said both should be ready to go Friday night.

“It was just kind of one of those where you get hit and it’s feeling really bad at the time but I feel better now,” Meier said.

The Sharks will open SAP Center Friday night against the rival Golden Knights, with puck drop scheduled at 7:30 p.m.

They’ll skate again Friday morning, when we may learn more about Karlsson’s availability.
