Ullmark -- who was originally expected to start against Buffalo on Wednesday -- is in doubt after suffering an undisclosed injury during morning skate. Coach Bruce Cassidy told reporters the starter would now be a game-time decision.
Based on the fact that Cassidy referred to Ullmark's injury as a tweak, he might still be available to serve as the backup if not deemed fit enough to start. The 28-year-old Swede has been splitting the crease with Jeremy Swayman and will likely continue to do so down the stretch.
