Contrary to a prior report, Ullmark is contending with an illness and will not be available Monday against Team USA, according to Elliotte Friedman of Sportsnet.

EDGE Analysis

Samuel Ersson will get the start in place of Ullmark at TD Garden in Boston. The Swedes will be playing for pride Monday -- the Americans will face Team Canada in the 4 Nations Face-Off Final on Thursday. Ullmark will have plenty of time to recover before the Senators resume play Saturday against Montreal.

Ullmark was the first goalie off the ice Monday, Fluto Shinzawa of The Athletic reports, indicating he'll be between the pipes for Sweden's game against Team USA.

EDGE Analysis

Ullmark saw action in relief of Filip Gustavsson against Finland on Saturday and will now get the starting nod for a crucial matchup with the Americans. In his two appearances with Ottawa following his extended absence due to a back injury, the 31-year-old netminder underwhelmed, giving up seven goals on 84 shots (.917 save percentage) in a pair of defeats. He'll need to perform significantly better if Sweden is going to make the championship game of the 4 Nations Face-Off.

Ullmark took over the Swedish net Saturday to start the second period of their 4-3 overtime loss to Finland at the 4 Nations Face-Off in Montreal. He made 15 saves.

EDGE Analysis

Filip Gustavsson had seemed off his game in the warm-up, and he allowed two goals on four shots in the first period before leaving with an illness. Ullmark was solid, but he got fooled in OT when Mikael Granlund came in on the right side of a 3-on-1, looking pass all the way, before threading the puck through the five-hole. The Swedes play Team USA on Monday in Boston. We'll know more about who'll get the net then.

Ullmark made 43 saves Saturday in a 5-1 loss to Florida.

EDGE Analysis

He allowed four goals, all of which came in the second period. Ullmark was flat-out shelled Saturday, with 26 shots coming in the first half of the game. His defense was suspect, and he should have had Gustav Forsling's goal, which came on a long, unobstructed shot. But this loss wasn't on him. Ullmark is still waiting for his first win since his return from injury (0-2-0), so that may come at the 4 Nations Face-Off, which starts next week.

Ullmark will guard the visiting net in Florida on Saturday, TSN 1200 Ottawa reports.

EDGE Analysis

Ullmark returned to action Tuesday after missing 19 games with a back injury. He looked sharp despite absorbing a 4-3 loss, stopping 34 of 37 shots in Tampa Bay. Ullmark is 12-8-2 with three shutouts, a 2.41 GAA and a .915 save percentage. The Panthers are generating 3.27 goals per game, sixth in the league this season.

Ullmark (back) made 34 saves in a 4-3 loss to Tampa Bay on Tuesday.

EDGE Analysis

The Bolts spoiled his return from injury -- he hadn't played since Dec. 22 (18 games) because of a back injury. Ullmark is 12-8-2 this season with a 2.41 GAA and .915 save percentage. Back injuries can be tricky, but he wouldn't be in net if he wasn't ready. Get Ullmark in your net -- he's too talented to ride the pine.

Ullmark will guard the road goal versus the Lightning on Tuesday, TSN 1200 Ottawa reports.

EDGE Analysis

Ullmark will make his long-awaited return to the crease after missing 18 games. He suited up Monday in Nashville as the backup to Anton Forsberg for the Senators' 5-2 win over the Predators. Ullmark is 12-7-2 with a 2.38 GAA and a .915 save percentage over 23 appearances this season and will get a tough matchup right away against a Lightning team that's averaging 3.45 goals per game, third-best in the NHL.

Ullmark (back) was activated from long-term injured reserve Sunday, per the NHL media site.

EDGE Analysis

Ottawa assigned Leevi Merilainen to AHL Belleville in a corresponding move. Ullmark could return to the crease in Monday's road matchup versus Nashville after missing the last 18 games. He has posted a 12-7-2 record with three shutouts, a 2.38 GAA and a .915 save percentage across 23 appearances this season.

Ullmark (back) won't be available to serve as a backup for Thursday's home game against the Capitals, TSN 1200 Ottawa reports.

EDGE Analysis

Ullmark remains on long-term injured reserve due to his back injury, but he was working in a net during Thursday's morning skate, fueling speculation that he'd be cleared to serve as Anton Forsberg's backup. However, Ullmark will require at least one more game on the shelf, while Leevi Merilainen will serve as the No. 2 netminder against Washington. Ullmark's next chance to suit up will be at home against Minnesota on Saturday.

Ullmark (back) might be an option against either the Capitals or Wild on Thursday or Saturday, respectively, Bruce Garrioch of Postmedia reports.

EDGE Analysis

Ullmark was riding a seven-game winning streak prior to suffering his back injury, which has kept the netminder on the shelf since Dec. 22 versus Edmonton. Once the 31-year-old backstop is given the all-clear, he figures to replace Leevi Merilainen as the No. 1 option in Ottawa, though he could be forced into more of a split share to start.
