Wallstedt is dealing with an illness and is unlikely to dress against the Canadiens on Monday, Michael Russo of The Athletic reports.

Wallstedt has given up three or more goals in each of his last five contests, posting a 2-3-0 record and 4.44 GAA. The 23-year-old backstop may not have featured in Monday's game anyway, so it's unlikely he is missing a start. Filip Gustavsson will get the nod versus the Habs while Cal Petersen could be called up from the minors to serve as the backup.

Stevenson will defend the home crease against the Islanders on Monday, Sammi Silber of The Hockey News reports.

Stevenson made his first start of the season for the Capitals at home against Carolina on Saturday, turning aside 19 of 22 shots (.864 save percentage) in a 4-3 overtime victory, marking his first win at the NHL level. He'll have a more favorable matchup against the Islanders, who are scoring 2.84 goals per game this year, which is the ninth-worst mark in the league.

Thompson (upper body) will not be in action versus the Islanders on Monday, Sammi Silber of The Hockey News reports.

According to Silber, the Capitals are hoping that Thompson can suit up against the Predators on Thursday. With Clay Stevenson getting the nod at home Monday, fantasy managers should probably expect Garin Bjorklund to make his NHL debut in Tuesday's matchup against the Flyers. As such, Thompson figures to miss both ends of Washington's back-to-back.

Ullmark will defend the road net against Pittsburgh on Monday, Jackson Starr of the Senators' official site reports.

Ullmark is coming off a 26-save performance in Saturday's 4-1 win over New Jersey. He has posted a 15-8-5 record this season with a 2.89 GAA and an .884 save percentage across 29 appearances. Pittsburgh is tied for fifth in the league with 3.40 goals per game this campaign.

Rittich was the first goalie off during Monday's morning skate, Stefen Rosner of NHL.com reports, indicating that he'll draw the road start against Washington.

Rittich has seen limited playing time in recent weeks, but he'll tend the twine in the first half of a back-to-back set Monday. Across six appearances in January, he went 2-3-1 with a 3.31 GAA and .838 save percentage. The Capitals are generating 3.18 goals per game this year, which is tied for 14th in the league.

Gustavsson will start Monday's home game against the Canadiens, Jessi Pierce of NHL.com reports.

Gustavsson got the night off Saturday against Edmonton, but he'll return to the crease two days later. Across his last five starts, he's gone 4-0-1 with a 2.95 GAA and .901 save percentage, with two of those victories coming in overtime. The Canadiens are scoring 3.44 goals per game this year, which ranks fourth in the NHL.

Kolosov was recalled from AHL Lehigh Valley on Monday.

Kolosov was sent to the minors Sunday, but he'll rejoin the NHL club a day later, which could signal that Samuel Ersson (lower body) will be unavailable for a second consecutive game Tuesday at home against Washington. Kolosov has made four appearances for the Flyers this year, going 0-2-0 with eight goals allowed on 47 shots (.830 save percentage).

Silovs was the first goalie to leave the ice Monday, Seth Rorabaugh of Tribune-Review Sports reports, indicating he'll be in goal at home versus the Senators.

Silovs will take the first game of the Penguins' back-to-back to continue an every-other-game trend in the crease. In his last nine appearances, the backstop has suffered just one regulation defeat, going 6-1-2 with a 2.50 GAA and .902 save percentage. With the upcoming Olympic break, Stuart Skinner may take the final two games before the break, especially with Silovs headed to Milan as part of the Latvian squad.

Bobrovsky was the first goalie off during Monday's morning skate, George Richards of Florida Hockey Now reports, indicating that he'll draw the home start against the Sabres.

Bobrovsky has alternated starts with Daniil Tarasov over the past few weeks, but the former will draw a second consecutive start Monday for the first time since mid-January. Bobrovsky is in the midst of a cold spell in which he's gone 1-4-0 with a 4.00 GAA and .839 save percentage over his last five outings.

Hill stopped 19 of 22 shots in Sunday's 4-3 loss to the Ducks. The fourth goal was an empty-netter.

The Golden Knights ran out of time after Tomas Hertl brought the deficit back to one late in the third period. Hill took his third straight loss (0-2-1), and he's allowed 14 goals on 81 shots in that span. For the season, the 29-year-old goalie is 3-3-3 with a 3.51 GAA and an .856 save percentage over 11 contests. Both Hill and Akira Schmid are likely to get one more start prior to the Olympic break, as the Golden Knights host the Canucks on Wednesday and the Kings on Thursday in a back-to-back set.
