Trevor Lewis was placed on injured reserve by the Los Angeles Kings on Monday because of a lower-body injury.
The forward did not play in a 3-2 loss to the Montreal Canadiens on Saturday after he was injured in a 3-2 overtime loss to the Ottawa Senators on Thursday.
"It's probably a little longer than what we originally anticipated so he'll need some time to recover," Kings coach Todd McLellan said Saturday.
Lewis has two points (one goal, one assist) in 16 games this season.
Selected by Los Angeles in the first round (No. 17) of the 2006 NHL Draft, Lewis has 153 points (65 goals, 88 assists) in 634 regular-season games with the Kings and 23 points (11 goals, 12 assists) in 79 Stanley Cup Playoff games. He has won the Stanley Cup twice with Los Angeles (2012, 2014).
