Bill Walker will miss the next four to six weeks as he will undergo left elbow debridement surgery, the New York Knicks announced Sunday. The news was initially tweeted by Tina Cervasio, Knicks courtside reporter.

Walker, a 6-foot-6 forward, was averaging 6.1 points and 2.7 rebounds per game this season. He started eight games for the Knicks earlier in the season, but has been relegated to the sidelines recently by the signing of J.R. Smith and the emergence of sharp-shooting Steve Novak.

Walker last played on Feb. 17. He has not made an appearance in any of the Knicks last five games.

Walker is in his fourth NBA season, and has been with the Knicks since midway through the 2009-2010 season after beginning his career with the Boston Celtics. He averages 5.8 points and 2.1 rebounds per game for his career.
