Ullmark will be between the home pipes versus Florida on Thursday, Julian McKenzie of The Athletic reports.
Ullmark will get the Opening Night assignment after the Senators dealt with Boston in the offseason to bring in the netminder. Ullmark was 22-10-7 with a 2.58 GAA and a .915 save percentage with the Bruins last year, one season removed from his 40-6-1 Vezina Trophy-winning campaign in 2022-23. Ullmark gets a tough assignment as the Panthers are the defending Stanley Cup champions.
