McAvoy has not played since December 7th, missing two games, and has now been retroactively placed on the injured reserve. Before his injury, McAvoy had four points (0G / 4A) in his last five games. In a corresponding move defenseman Parker Wotherspoon has been recalled from the Providence Bruins of the AHL.

Kastelic has not played since November 2nd when he suffered a high-ankle sprain that has subsequently kept him out of the lineup for approximately six weeks. Kastelic had zero points in nine games before his injury, averaging 6:55 time-on-ice. At morning skate on Thursday, he skated on the fourth line with Parker Kelly and Rourke Chartier.

After serving as the backup for three straight games, Korpisalo will likely start for his third consecutive game on Thursday. The Senators coaching staff has been quick to deviate to a different goaltender after a poor performance but will stick with Korpisalo on Thursday despite allowing four goals on 28 shots (.857 SV%) in a 4-1 loss to the Carolina Hurricanes. In addition, Korpisalo has lost three of his last four contests (1-3-0) and has only one quality start in the bunch, posting a .882 SV%. That said, the Senators are -118 road favourites against a St. Louis Blues team that has lost four straight, being outscored 20-10.

After consecutive poor performances led him to serve as the backup for three straight games, Korpisalo rebounded on Saturday, saving 30 of 31 shots (.968 SV%) in a 5-1 win over the Detroit Red Wings and will look to build on that performance as the starter on Tuesday. Korpisalo has strung together stretches of solid play this season, but is still showcasing a less-than-ideal 3.22 GAA and .903 SV% through 14 games (6-6-0). The Senators have won three of their last four (3-1-0) but are +117 home underdogs against the Carolina Hurricanes, who have lost four straight, being outscored 15-7.

McAvoy played only 15:53 time-on-ice on Thursday before exiting the game with a shoulder injury. The 25-year-old defenseman did not play on Saturday and has been ruled out for Wednesday's matchup against the New Jersey Devils. His status remains to be determined for the team's next contest on Friday against the New York Islanders. Kevin Shattenkirk has assumed McAvoy's duties on the top powerplay in his absence.

Zacha exited Saturday's contest against the Arizona Coyotes with an upper-body injury after playing only 6:42 time-on-ice and has been ruled out of action on Wednesday against the New Jersey Devils. His status remains to be determined for the team's next contest on Friday against the New York Islanders. Zacha has centred the top line and top powerplay unit all season, scoring 19 points (8G / 11A) in 26 games, averaging 18:22 time-on-ice. Morgan Geekie is expected to center the top line between Jake DeBrusk and David Pastrnak during Zacha's absence and assume duties on the top powerplay.

Harris has not played since November 18th, missing 10 consecutive games, and will miss an additional 10-14 days as he recovers from a lower-body injury. The 23-year Harris was averaging 18:45 time-on-ice and had three points (0G / 3A) through 16 games this season.

Morgan Geekie is expected to center the top line between Jake DeBrusk and David Pastrnak during Zacha's absence.

Brandon Bussi was recalled on Thursday to backup Linus Ullmark as Swayman was out of the lineup battling an illness. The starting goalie has not been announced yet for Saturday's contest against the Arizona Coyotes but if called upon, Swayman will be ready to suit up after returning to practice on Friday. Swayman has been tremendous lately, saving 50 of the last 51 shots he has faced (.980 SV%) during a two-game winning streak.

McAvoy played only 15:53 time-on-ice on Thursday before exiting the game with a shoulder injury. The 25-year-old defenseman did not participate in practice on Friday, and is considered day-to-day but hopeful to play Saturday. If McAvoy misses any time, look for Hampus Lindholm to move up to the top powerplay unit, where he saw success last season when McAvoy was out of the lineup.
