Isles offer Nabokov extension, trade vets

The Islanders made one late move, sending veterans Brian Rolston and defenseman Mike Mottau to Boston in the final minutes before the clock struck three. They received prospects Yannick Riendeau and Marc Cantin from the Bruins in the deal.

In addition to the last-minute swap, general manager Garth Snow extended an offer to goaltender Evgeni Nabokov, who is slated to become an unrestricted free agent July 1. Nabokov is currently mulling the deal, one source confirmed to ESPNNewYork.com.
