Lauko had been unavailable the previous two games after suffering an upper-body injury in Saturday's game against the Kings. Justin Brazeau will sit in his place.

Mitchell hasn't made an appearance for the Bruins since December 23rd. He has no goals and two assists in 13 games this season.

Linus Ullmark had a rough outing in his last contest, allowing five goals on 35 shots (.857 SV%) in a 5-4 overtime loss to the Los Angeles Kings, opening the door for Swayman to break Boston's typical goalie rotation and start back-to-back games. Swayman was spectacular against the Stars on Monday, stopping 43 of the 46 shots he faced enroute to a 4-3 shootout victory. The Bruins enter action as +118 road underdogs against the Edmonton Oilers and their fifth-ranked offense (3.56 GF / GP).

Parker Wotherspoon and Lorei are both drawing into the Bruins' lineup on Wednesday as Hampus Lindholm (undisclosed) and Kevin Shattenkirk (healthy scratch) are both not expected to play. Lohrei has not played for the Bruins since January 18th and has six points (3G / 3A) in 27 games this season.

Mason Lohrei and Wotherspoon are both drawing into the Bruins' lineup on Wednesday as Hampus Lindholm (undisclosed) and Kevin Shattenkirk (healthy scratch) are both not expected to play. Wotherspoon last played on February 15th and registered a -1 plus/minus and one hit in 14:01 time-on-ice.

Lindholm is not expected to play on Wednesday as he is dealing with an undisclosed injury and is now considered out week-to-week. The 30-year-old defenseman has 19 points (1G / 18A), 71 shots, and 73 blocks in 56 games. Parker Wotherspoon and Mason Lohrei are both expected to back into the lineup for the Bruins.

Korpisalo will man the Senators' crease for the third time in four games after backing up Anton Forsberg in Ottawa's previous game. The 29-year-old is in the first of a five-year, $20 million contract in the offseason and has been highly underperforming with his 13-18-2 record, 3.41 GAA and .887 SV%. He takes on one of the NHL's hottest teams in Florida, who has won five straight and nine of their last 10 while leading the NHL in shots on goal per game (34.0).

Poitras missed the Bruins' previous game before the All-Star break due to the injury and did practice in full on Sunday, but the team and Poitras have opted for surgery to repair his injured shoulder, bringing a premature end to his rookie season. The 19-year-old rookie left the Bruins briefly in December to attend this year's World Jr Tournament and has made a solid impact in his rookie season with five goals and 15 points in 33 games played.

Lohrei hasn't played a game for Boston since January 18th and has primarily been with the Providence Bruins (AHL) since. The 23-year-old defender has excelled at the AHL level this season with 13 points (1G / 12A) in 17 games.

Lindholm left Monday's game after 18:09 TOI due to an undisclosed injury and will be evaluated on Tuesday to declare the extent of his injury. The 30-year-old defenseman is a key piece in Boston's impressive defensive unit and has a goal, 18 assists, 73 SOG, 54 PIMs and a +19 plus/minus through 57 games this season.

Lauko recorded an assist but played only 8:16 time-on-ice after suffering an upper-body injury. Newly signed Justin Brazeau will make his NHL debut in Lauko's absence.

As has been the case most of the season, the Bruins will continue to alternate goalies and turn to Swayman on Monday after Ullmark played on Saturday. Swayman has a sub-.900 SV% in two of his last three games (0-3-0), a rarity for the All-Star netminder. The Bruins are -134 home favourites against a Dallas Stars club without their number one defenceman Miro Heiskanen (personal).

Wotherspoon continues to rotate with Kevin Shattenkirk as the former will take a seat on Thursday. Wotherspoon has no goals and three assists in 22 games this year.

As has been the case most of the season, Swayman will tend the twine on Thursday, replacing Linus Ullmark, the starter in the Bruins' previous contest. Swayman has lost consecutive games in regulation, a first-time occurrence for the All-Star netminder, allowing six goals on 57 shots and posting an uncharacteristically low .895 SV%. That said, the Bruins are -181 home favourites against a Seattle Kraken club with only three wins in their last 10 games (3-6-1).

Korpisalo had the night off on Tuesday, a 6-3 win over the Columbus Blue Jackets, but will return to the crease on Thursday as the Senators attempt to extend their four-game winning streak. Korpisalo has been excellent lately, winning three straight while allowing three or fewer goals in each and posting a .935 SV%. The Senators are sizeable -202 home favourites against an Anaheim Ducks squad that was limited to only 13 shots on goal in their last contest, a 5-0 loss to the Montreal Canadiens.
