Rittich will start Sunday's preseason game against the Islanders, per Amanda Stein of the Devils' official site.
For his debut with New Jersey, Rittich will have the chance to face the Islanders, for whom he played last season. The 34-year-old netminder was a decent backup option in 2025-26, as he posted a 14-10-3 record, a 2.76 GAA and an .894 save percentage across 30 regular-season games for the Isles. The veteran netminder is competing for a larger role this preseason against Jake Allen.
