Sanderson (upper body) is week-to-week, Jackson Starr of the Senators' official site reports Monday.

Sanderson sustained the injury in Saturday's 7-4 win over Seattle. He has compiled 11 goals, 48 points, 133 shots on net and 116 blocked shots across 62 appearances this season. With Sanderson unavailable, Nikolas Matinpalo (undisclosed) will return to action from an injury, and Thomas Chabot will receive an increased role in the lineup.

Fabbro (lower body) will be a game-time decision versus the Kings on Monday, Mark Scheig of The Hockey Writers reports.

Fabbro has already missed two games due to his lower-body problem and could be in danger of missing a third. Over 54 games this year, the 27-year-old blueliner has managed just four goals and five assists, well off his pace from last season, in which he notched 26 points in 68 games between the Predators and Blue Jackets.

Heiskanen scored the game-winning goal in Sunday's 4-3 overtime win over Chicago.

Heiskanen found the back of the net just 22 seconds into overtime to give the Stars the win, extending the team's point streak to 12 games. The star blueliner has been very productive of late and has cracked the scoresheet in eight of his last nine appearances, a span in which he's racked up 12 points (two goals, 10 assists), 25 shots, four hits and 16 blocked shots.

Whitecloud (upper body) didn't travel with the Flames for their five-game road trip, Eric Francis of Sportsnet reports Monday.

While the team hopes Whitecloud will be able to join them at some point during the trip, his absence figures to keep him out for at least the back-to-back versus the Capitals and Rangers on Monday and Tuesday, respectively. With Whitecloud unavailable, Joel Hanley will return to the lineup after missing Saturday's contest versus Carolina due to an illness.

Hanley (illness) is expected to be back in the lineup versus the Capitals on Monday, Derek Wills of Sportsnet 960 The Fan reports.

Hanley will be back in action after missing just one game due to his illness. The defenseman has yet to score a goal in 58 games this season and has managed just one helper in his previous 22 outings. Given his lack of offensive upside, fantasy managers will want to pursue alternative fantasy options on the blue line.

Karlsson pocketed two assists, including one on the power play, in Sunday's 5-4 overtime win over the Bruins.

The veteran blueliner had a hand in tallies by Yegor Chinakhov in the second period and Anthony Mantha in the third, the latter of which forced OT. Karlsson has been building momentum since the Olympic break with two goals, seven points and 20 shots on net over his last six games.

Gilbert was recalled from AHL Belleville on Monday.

Gilbert's promotion to the NHL roster doesn't bode well for the availability of Jake Sanderson (upper body) for Monday's game versus Vancouver, especially with Nikolas Matinpalo (undisclosed) recovering from an injury of his own. If Gilbert suits up Monday, it would be just his second NHL game of the year -- he logged 13:50 of ice time against the Rangers on Dec. 4.

Aspirot notched two assists in Sunday's 5-4 overtime loss to the Penguins.

The assists came in the second and third periods as Aspirot helped Pavel Zacha complete his second career hat trick. The 26-year-old blueliner has yet to score a goal in 2026, going 21 games without finding the back of the net, but he's been productive on an even-strength pairing with Charlie McAvoy. Over his last nine games, Aspirot has seven assists, 12 blocked shots, 10 hits, six PIM, five shots on net and a plus-3 rating.

Brunet signed a two-year, $1.75 million contract extension with Boston on Monday.

It's a two-way contract for the 2026-27 season before becoming a one-way agreement for the 2027-28 season. Brunet has produced 11 goals and 28 points in 55 appearances for AHL Providence this campaign. He made his NHL debut with Boston in 2024-25, posting five blocked shots in 14:23 of ice time against New Jersey on April 15, 2025.

Seider scored a goal, supplied two assists and fired five shots on net in Sunday's 3-0 win over New Jersey.

Seider netted Detroit's first goal of the contest in the opening period before he later recorded a helper in each of the final two frames. Sunday's effort was his second three-point outing of the campaign and brought him up to eight goals, 36 assists, 137 shots on net, 103 hits and 142 blocked shots over 64 games this season. With the Red Wings trending towards ending their playoff drought, Seider should continue to operate at the heart of the team and post elite category-coverage stats for fantasy purposes.
