Just four games after making his season debut, Los Angeles Kings forward Viktor Arvidsson returned to long-term injured reserve Saturday.

Arvidsson will be sidelined with a lower-body injury after missing the first 50 games of the season following back surgery in October.

Former Ottawa Senators coach D.J. Smith was hired as an assistant coach by the Los Angeles Kings on Tuesday.

General manger Rob Blake said Monday the Kings were looking to hire an assistant coach from outside the organization after Jim Hiller was named interim coach. Hiller was promoted last Friday after Todd McLellan was fired after four-plus seasons as head coach.

The Los Angeles Kings have fired coach Todd McLellan and replaced him with interim coach Jim Hiller for the rest of the season, the team announced Friday.

Replacing McLellan is the latest development for the Kings in a season that has seen them go from once leading the Pacific Division and reinforcing why they were preseason Stanley Cup contenders to entering the NHL All-Star break in the first of two Western Conference wild-card spots.
