LAS VEGAS -- The slumping Vegas Golden Knights suffered another loss Thursday when they announced center William Karlsson is week-to-week with a lower-body injury.

The club recalled Tanner Laczynski and Brendan Brisson from its American Hockey League affiliate in Henderson, Nevada.

Karlsson, 32, has seven goals and 11 assists in 38 games this season, well off the pace of the 30-30 mark he posted last year. He doesn't have a point in his past seven games.

The Golden Knights entered Thursday's game at St. Louis first in the Pacific Division with 62 points. But they were 1-5-1 in their previous seven games, allowing the Edmonton Oilers to creep to within a point.

Karlsson has dealt with injuries in recent years, appearing in 70 or fewer games in four of the past five seasons. He played in all 82 games two years ago.

Karlsson missed the first eight games this season because of a hamstring injury he sustained in last season's playoffs.
