Ottawa Senators goaltender Linus Ullmark leaves the game after two periods against the Boston Bruins on Monday night, and he does not play in the third period. His team’s backup, Samuel Ersson, replaces him at that point.

The reports do not immediately specify the reason for the change. Both outlets note that it is unclear why Ullmark is not in net after the second intermission, with the timing suggesting the decision occurs between periods. The coverage focuses on the lineup change rather than any diagnosed injury or other cause at the time of reporting.

No further details about the circumstances are provided in the available accounts, including whether the move is tactical or related to health. Additional information would depend on later updates from team officials or game follow-ups.
