Kidney was a second-round pick of the Montreal Canadiens in the 2021 NHL Entry Draft, but has yet to play an NHL games. The 22-year-old forward spent the last two seasons with the Laval Rocket (AHL), but has spent most of 2025-26 in the ECHL, where he has 33 points (11G / 22A) in 46 games with the Trois-Rivieres Lions.
Jensen only played 14:28 time-on-ice in Ottawa's 3-2 loss to the Montreal Canadiens on Wednesday, and was absent from practice on Friday. It is unclear if he will be ready to play when Ottawa returns to action on Saturday afternoon against the Anaheim Ducks.
Ullmark has battled some adversity in recent games, allowing four or more goals twice in his last three, but has salvaged a 2-0-1 record despite posting a subpar 3.29 GAA and .872 SV%. That said, the 32-year-old Swedish goalie has played reasonably well since returning from a multi-week personal leave of absence in late January, posting a 2.41 GAA and .896 SV% in seven games (5-0-2). The Senators enter Wednesday's contest as -190 home favourites against a Montreal Canadiens team with points in three straight games (2-0-1).
Matinpalo will make his first appearance for the Sens since January 24th, slotting in for the injured Jake Sanderson (upper-body). Matinpalo is yet to score a goal and has just four assists in 30 games this season.
The Senators have relied exclusively on Linus Ullmark since returning from the Olympic break, but will turn to Reimer on Monday against the Vancouver Canucks for his first start in over a month. The 37-year-old Reimer showcased mixed results since making his Senators' debut in mid-January, but he was excellent in his most recent game, saving 15 of 16 shots (.938 SV%) in a 2-1 win over the Philadelphia Flyers. The Senators enter Monday's contest as significant -220 road favourites against a reeling Canucks team that has a dreadful league-worst -71 goal differential through 63 games (19-36-8).
Sanderson was limited to 12:52 time-on-ice in Saturday's 7-4 win over the Seattle Kraken, exiting with an undisclosed injury, and, after undergoing further testing, has been ruled out on a week-to-week basis. The 23-year-old Sanderson has been held off the scoresheet in three straight games, but has 48 points (11G / 37A) in 62 games this season and will be sorely missed by a surging Senators' team that makes a late-season playoff push. With Sanderson sidelined, expect Thomas Chabot to take his spot on the team's top powerplay unit.

Ullmark struggled in his previous game, allowing five goals on 37 shots (.865 SV%) in a 5-4 overtime loss to the Edmonton Oilers, and hopes to redeem himself on Thursday against the Calgary Flames.

Kaliyev was a second-round pick in the 2019 NHL Entry Draft, but has been unable to establish himself at the NHL level. That said, the 24-year-old forward has been extremely effective in the AHL this season, scoring 50 points (30G / 20A) in 52 games with Belleville.
Stutzle played well for Team Germany at the Olympics, scoring six points (4G / 2A) in five games, and is healthy enough to return to the Sens lineup on Thursday. The 24-year-old Stutzle is having a terrific season, with 61 points (28G / 33A) through 57 games. He had 10 points (6G / 4A) while riding a seven-game point streak heading into the Olympic break.

Ullmark did not play in Ottawa's final game before the Olympic Break due to an illness, but he will suit up Thursday against the Detroit Red Wings.

Ottawa needs a strong finish to the season to return to the playoffs, beginning by entering Thursday's game as -151 home favourites against a Red Wings team that defeated them 4-3 in their previous meeting.
