Dubielewicz went 16-13-1-1 with a 2.55 goals-against average over parts of four seasons with the Islanders through the end of last year.
After the club did not offer him a contract in the offseason, Dubielewicz signed with Ak Bars Kazan of the Continental League in Russia. He was 11-8-3 in 21 games, posting a 2.77 GAA.
Completion of the deal is contingent upon his Russian team granting his release, plus his clearing waivers once he returns to New York.
With injuries to starting netminder Rick DiPietro and backup Joey MacDonald, the Islanders are expected to use Yann Danis as the starter until Dubielewicz is cleared for NHL action.
