DiPietro had surgery to fix a knee and a hip during the offseason and didn't play the first four games of the season. While he wasn't ready for action then, he did dress for all the games as the backup to No. 2 goalie Joey MacDonald.
He finally made his first on-ice appearance on Oct. 18 at Florida and started three consecutive games. DiPietro lasted only one period Saturday night at home against Carolina, allowing two goals on 12 shots. One of the goals came directly after he turned over the puck with an ill-advised clearing attempt.
Following the game, the Islanders announced he was pulled because of an injury and not based on his performance. DiPietro was examined by a doctor on Monday, but no details were provided.
"Rick DiPietro incurred a lower body injury Saturday night unrelated to his previous injuries," according to a release provided by the team. "Rick is day-to-day pending additional assessment and treatment. No further comments related to this issue will be made until further information is available."
Yann Danis, recalled from AHL Bridgeport on Sunday, dressed as MacDonald's backup against the Rangers.
The Islanders have adopted a policy not to release specifics about injuries to players other than the general area -- upper or lower body. However, the team did say that defenseman Freddy Meyer sat out Monday with an abdominal strain that he sustained Saturday.
Elsewhere on the injury front, defenseman Brendan Witt missed his second straight game and is expected to be sidelined three to four weeks because of a lower body injury.
