The NHL’s department of player safety announced the fine Sunday.
The incident occurred early in the second period of the Kings’ 3-2 overtime win over the Sharks on Saturday. Wagner left the game after getting taken down by Karlsson on a hard hit near center ice. After getting back on his feet, Wagner’s legs came out from under him. No penalty was called.
Karlsson, who has points in eight consecutive games, has two goals and 24 assists this season for San Jose.
Karlsson, who joined the Sharks in an offseason trade with Ottawa, will miss games against the Ducks and Oilers after the holiday break. He will return on New Year’s Eve against Calgary.
