Korpisalo will patrol the home crease in Tuesday's exhibition matchup against Washington, per Conor Ryan of The Boston Globe.
Korpisalo compiled a 21-26-4 record with a 3.27 GAA and an .890 save percentage across 55 regular-season outings for Ottawa in 2023-24. He could start the upcoming campaign as Boston's No. 1 netminder if Jeremy Swayman, a restricted free agent, remains unsigned.
