Samsonov (COVID-19 protocols) didn't participate in Saturday's morning skate and will miss Game 1 against the Bruins, Samantha Pell of The Washington Post reports.
Vitek Vanecek will get the start in his playoff debut, while Craig Anderson's set to work in a backup role. Samsonov will hope to clear the protocols in time for Monday's Game 2, though it remains to be seen whether he'll unseat Vanecek as starter once available.
