Andreoff signed a two-year, two-way contract with the Islanders on Saturday, per PuckPedia.
Andreoff had 42 points in 60 games with AHL Bridgeport last season, but he only appeared in six NHL contests. His new contract is a two-way deal in both seasons, so Andreoff will likely remain on the fringe between the AHL and NHL as a depth forward for the Islanders.
