UNIONDALE, N.Y. -- Islanders defenseman Andy Sutton tore a hamstring and will be sidelined from four to six weeks.
Sutton was injured in the closing seconds of Monday's 3-2 victory over San Jose and was helped off the ice. An MRI taken Tuesday revealed a partial tear of the hamstring.
Witt, who was replaced by Sutton on New York's top defensive pairing with Radek Martinek, has missed three games since spraining his knee Feb. 12 and is expected to be out 1-to-2 more weeks. Gervais is day to day with an oblique strain that has forced him to sit out four games.
In January, New York lost defenseman Chris Campoli to a season-ending shoulder injury.
The Islanders, who play at Washington on Wednesday, recalled defenseman Drew Fata from Bridgeport (AHL). In 48 games with the Sound Tigers, Fata had three goals, five assists and 156 penalty minutes. He had one goal in three games for the Islanders last season.
