The Kings made the move on Wednesday, before their game atVancouver.
Toffoli has missed the Kings' past two games with a lower-body injury, and he will miss at least three more. He is the Kings' second-leading scorer, with 20 points in 32 games, including eight goals and a team-leading plus-14 rating.
The move allows Los Angeles to clear a roster spot for the eventual return of defenseman Brayden McNabb, who has been out since breaking his collarbone in late October.
The Kings haven't played a home game since Dec. 10. After two more road games in Canada, they will return to host theSan Jose Sharkson New Year's Eve.
