DiPietro, who was placed on waivers Friday, has eight years remaining on his contract at $4.5 million per season. Injuries and ineffective play have stalled the career of the No. 1 pick in the 2000 NHL Draft.
Including three games this season, DiPietro has only appeared in 50 for the Islanders since the start of the 2008-09 campaign. He has wins in 14 of those appearances.
To replace DiPietro on the roster, the Islanders recalled Kevin Poulin from Bridgeport. Poulin, a fifth-round pick in the 2008 NHL Draft, has appeared in a total of 16 games for the Islanders in the previous two seasons.
