Ullmark (undisclosed) won't start Wednesday versus the Sabres, but he is dressed as the backup, Mike Harrington of The Buffalo News reports.

EDGE Analysis

Ullmark tweaked something in Wednesday's morning skate, but his presence as the backup suggests he could play in a pinch. The Swede's next chance to start is Friday versus the Rangers.

Ullmark -- who was originally expected to start against Buffalo on Wednesday -- is in doubt after suffering an undisclosed injury during the game-day skate. Coach Bruce Cassidy told reporters the starter would now be a game-time decision.

EDGE Analysis

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, limiting him to a mid-range fantasy option.

Ullmark made 29 saves Saturday in a 5-2 win over the Flyers.

EDGE Analysis

It was Ullmark's first win in November (1-2-0) and the two goals allowed were a nice rebound from the nine he allowed in his previous two games.

Ullmark made 23 saves in a 5-3 loss to the Oilers on Saturday.

EDGE Analysis

Here's the thing. Ullmark had the Bruins up 3-2 early in the third period and then his mates soiled the bed. After the game, coach Bruce Cassidy was blunt: "We absolutely beat ourselves tonight, 100 percent." Ullmark should rebound, but it's worth noting he's 1-3 in his last four starts against some high power offense: Florida, Toronto and Edmonton.

Ullmark will defend the blue paint during Thursday's home game versus the Oilers.

EDGE Analysis

Ullmark wasn't great in his last start Saturday against the Maple Leafs, surrendering four goals on 35 shots en route to a 5-2 loss.

Ullmark made 31 saves Saturday in a 5-2 loss to Toronto. He allowed four goals.

EDGE Analysis

He's been good in black and gold this season, but the boys in blue and white had his number Saturday. Ullmark was at the mercy of guys crashing his crease and delivering on PPs. He'll put this behind him and be ready next time out.

EDGE Analysis

In four games this year, Ullmark has posted a 3-1-0 record and 2.23 GAA, outplaying Jeremy Swayman and earning the bulk of the starts. Still, the 28-year-old Ullmark will need to continue playing well to hold onto the starting job.
