In announcing the move on Saturday before their game at Buffalo, the Islanders also recalled goalie Kevin Poulin from Bridgeport. Poulin is expected to take over the role of backup behind starter Evgeni Nabokov. Poulin has a 6-6-1 record in 16 career games with the Islanders over the previous two seasons.
DiPietro's demotion is the latest blow to the career of an oft-injured player, who's failed to play up to the 15-year, $67.5 million contract he signed before the 2006-07 season.
This season, DiPietro is 0-3 with a 4.09 goals-against average in three games. There are still eight years at $4.5 million per season remaining on DiPietro's landmark deal.
