Kings' Muzzin week to week after suffering injury Monday night

The Los Angeles Kings will likely be without one of their best defensemen for at least the next seven days.

Jake Muzzin is listed as week to week with an injury the club simply described as an upper-body ailment, according to FOX Sports West's Jon Rosen.

Muzzin took a big hit from Micheal Ferland in the second period of Monday's win over the Calgary Flames. He did not return.

Muzzin has already set career highs in assists (34) and points (42) in 74 games, while averaging nearly 22 minutes of ice time.

The Kings hold the first Western Conference wild-card spot but sit only one point above the Colorado Avalanche and two points ahead of the St. Louis Blues, with more games played than both clubs.
