D'Astous (lower body) is expected to be an option for Wednesday's home contest against the Maple Leafs, per Benjamin Pierce of the Lightning's official site.

D'Astous missed the Lightning's last five games before the Olympic break due to his injury. The team's blue line is almost at full strength, so it remains to be seen how the coaching staff will handle deploying its defensemen going forward. D'Astous has collected three goals (two game-winners), 17 points, 52 shots, 53 hits, 45 blocks and 57 PIM over 43 appearances in 2025-26.

Girard was traded to the Penguins from the Avalanche, along with a 2028 second-round pick, in exchange for Brett Kulak on Tuesday.

Girard's move could see him get power-play minutes on the Penguins' No. 2 unit, a role that has been missing this season with Colorado. Through 40 games with the Avs this season, the 27-year-old blueliner has notched just 12 points, but he could return to being a 30-plus point producer with an expanded role. He'll cost Pittsburgh more against the cap, $5 million AAV, but is under contract through next season and comes with the valuable second-round pick.

Lilleberg (undisclosed) will be activated from injured reserve ahead of Wednesday's game against Toronto, Benjamin Pierce of the Lightning's official site reports.

Following a 23-game absence, Lilleberg will return to the lineup against the Maple Leafs. He has supplied two goals, six points, 24 shots on net, 33 blocked shots and 53 hits through 32 appearances this season.

Hedman (lower body) said Tuesday that he will be ready for Wednesday's home game versus the Maple Leafs and expects to be in the lineup, according to Erik Erlendsson of LightningInsider.com.

Hedman sustained his lower-body injury during warmups of last Wednesday's quarterfinals matchup for Sweden against the United States and did not play as a result. The left-shot blueliner has already missed 34 games for the Lightning this season due to an elbow injury. The 35-year-old should be good for his role in all situations against Toronto, though his ice time might be relatively low in the first half of a back-to-back -- Tampa Bay will also face Carolina on Thursday.

Moore was summoned from AHL San Diego on Tuesday.

Moore spent the Olympic break in the minors, playing in three games. He hasn't earned a point in four AHL appearances this season. Moore has spent the majority of the 2025-26 campaign in the NHL, collecting two goals, seven assists, 39 shots on net, 63 blocked shots and 17 hits in 41 contests for the Ducks.

Simashev was recalled from AHL Tucson on Tuesday.

Simashev has split time between the NHL and AHL this season. He has one assist in 24 appearances with the big club in 2025-26 while notching seven goals and 25 points in 27 minor-league outings.

Lamoureux was promoted from AHL Tucson on Tuesday.

Lamoureux was called up alongside fellow blueliner Dmitri Simashev, which would seem to indicate there are some defenseman in doubt ahead of Wednesday's clash with the Avalanche. For his part, the 22-year-old Lamoureux has logged just five NHL games this year, tallying one assist, 11 hits and four shots along the way.

Kiersted was elevated from AHL Iowa on Tuesday.

Kiersted has appeared in just four NHL games this season, in which he notched one assist, four shots and five blocks while averaging 13:42 of ice time. The decision to bring Kierster up from the minors could be an indication that Quinn Hughes won't be back in time from the Olympics to face Colorado on Thursday.

Clague was recalled from AHL Manitoba on Tuesday.

The decision to bring Clague up from the minors could be an indication that Neal Pionk (lower body) won't be ready to return to action versus the Canucks on Wednesday. Even with injuries piling up on the blue line, the 27-year-old Clague figures to serve as a healthy scratch with Ville Heinola taking the open spot in the lineup.

Morrissey (upper body) was placed on injured reserve Monday, per the NHL media site.

Morrissey's placement on IR confirms that the blueliner will miss a period of time, which coincides with earlier reports Monday. The 30-year-old defenseman missed each of Canada's last five games at the 2026 Winter Olympics after leaving their first contest following a collision with Czechia's Ondrej Palat. Morrissey has compiled 10 goals, 42 points, 104 shots on net and 94 blocked shots across 56 games for Winnipeg this season. The Jets' task of rejoining the wild-card race in the Western Conference will be difficult without their lead defenseman, who will miss at least three games. His earliest chance to return is March 3 versus Chicago.
