UNIONDALE, N.Y. (AP) -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.

The Islanders will also be without captain Doug Weight when they host Atlanta on Saturday night. The 38-year-old center is expected to miss a week after sustaining an undisclosed upper body injury.

Weight has played in only 11 of New York's 16 games because of an early season groin injury and a bout with the swine flu.
