Before their road game against the Calgary Flames on Wednesday, the Kings announced Roenick underwent successful surgery on his broken left ring finger Thursday and will miss four to six weeks.
The surgery was performed by hand specialist Dr. Steve Shin at
the Kerlan Jobe Surgery Center on Thursday morning.
Roenick, 35, suffered the injury during the second period of Monday's shootout win over the Vancouver Canucks. He had a goal and an assist in that game, ending an eight-game streak without a point.
Earlier Monday, Roenick was not among the 23 players chosen to play in the 2006 Winter Olympics in Turin, Italy. A member of the United States' previous two Olympic teams, Roenick took offense to being snubbed despite managing only six goals and seven assists in 32 games this season.
"If they want to leave me off because of my numbers this year, that's well and fine," Roenick said after Monday's game. "They didn't invite me to camp in September and they've been blackballing me anyways.
"I know I can play this game at a high level. My stats aren't indicative of the way I've played this year. I think my career, the way I've worked, speaks for itself. If that's the way they want to be, it's fine. I'll accept it."
With 1,137 points, Modano has a four-point lead over Roenick. Retired defenseman Phil Housley leads U.S.-born players with 1,232 points.
Roenick, whose 481 career goals are 21 shy of Joe Mullen's standard for U.S.-born players, is in his first season with Los Angeles after previously playing for Chicago, Phoenix and Philadelphia.
Also on Wednesday, the Kings activated rookie George Parros from injured reserve. The 25-year-old right wing, who has missed the past 15 games with a right ankle sprain, has one goal, three assists and 47 penalty minutes in 20 games.
