New York Islanders defenseman Radek Martinek is out for the season with a knee injury. The Islanders announced on Saturday that Martinek tore the anterior cruciate ligament in his right knee on Friday night in the third period of a 2-1 loss at New Jersey. The oft-injured defenseman was helped off the ice with about 5:45 to play after he was hit hard against the boards in front of the Devils bench by Zach Parise.
