Rangers coach John Tortorella told reporters Friday that forward Mike Rupp will have arthroscopic surgery on his left knee next week. A timetable for Rupp's return will be determined after the surgery.
Tortorella also said that Wojtek Wolski, who re-injured his groin in Thursday's 2-1 shootout win over Anaheim, is expected to have an MRI and is definitely out for Saturday's game against Montreal. That means Sean Avery will make his season debut with the Rangers after clearing re-entry waiveres and getting recalled earlier in the week.
Backup goalie Martin Biron missed practice due to a death in the family, but will be back for Saturday's game. Henrik Lundqvist is expected to start against the Canadiens.
Tortorella said there was no further update on the status of Marc Staal (post-concussion symptoms). He reportedly used the word "indefinite" when asked about Staal's health status.
The Rangers could make a subsequent move to replace Wolski on the roster should he be out for an extended period, but they've done nothing as of yet. They also haven't officially announced the signing of defenseman Anton Stralman, who reportedly agreed to a one-year, $900,000 contract on Thursday.
