The Lightning recalled defensemen Sean Day and Declan Carlile from the AHL’s Syracuse Crunch on Thursday, a team release states. This transaction comes after the Lightning were forced to play their last game, a 4-2 loss to the Jets on Tuesday, with 13 forwards and five defensemen due to an injury to Erik Černák and no salary cap space available for a corresponding recall.

Thus, the Lightning must have made a corresponding transaction to fit Day and Carlile on the active roster. It’s possible the team has transferred defenseman Mikhail Sergachev from standard injured reserve to long-term injured reserve, which would rule him out of the team’s next five games with a lower-body injury. He’s already missed six games and 15 days with the injury, which he sustained in the first period of a Dec. 19 game against the Blues.

Day and Carlile now come up to the Lightning roster to provide reinforcements to a badly bruised blue line without two of its three best players in Černák and Sergachev. This isn’t new territory for Day, 25, who was recalled three times last month to serve as injury insurance but did not appear in a game. The one-time OHL exceptional status nod is in his fourth season with the Lightning organization and has made 17 appearances with Syracuse this year, recording eight assists and a +8 rating. He has not made an NHL appearance since logging a pair of games with the Lightning in the 2021-22 season.

For the 23-year-old Carlile, though, this is a career-first. Signed by the Lightning as an undrafted free agent after completing his junior season at Merrimack College in 2022, the Michigan-born defender earns his first in-season recall in the final year of his two-year, entry-level deal. It’s an important step en route to him potentially earning a qualifying offer at the end of this season and remaining in the Lightning organization.

The 2020 Hockey East All-Rookie Team nominee does his best work in transition, posting solid zone entry denial metrics at the collegiate and AHL levels. He was a monster two-way minutes-muncher for Syracuse last season, recording 24 points in 69 games throughout his first full pro season while posting a team-high +28 rating. His numbers this season (three goals, six assists, nine points, +8 rating in 31 games) aren’t quite as strong, but there’s still reason to believe NHL upside exists in Carlile’s game.

One of Day or Carlile will likely draw into the lineup in a third-pairing role alongside recent call-up Philippe Myers on Thursday when the Lightning visit the Wild. Day and Carlile are both left-shot defensemen.
