George was recalled from AHL Bridgeport on Tuesday, Stefen Rosner of NHL.com reports.

Ryan Pulock is dealing with a lower-body injury and is unavailable for Tuesday's home contest against Chicago, so George will serve as the Islanders' seventh defenseman for the time being following his promotion. The 22-year-old George has gotten into two games with the big club this season, notching an assist while averaging 13:18 of ice time. The left-shot blueliner has also provided two goals, 17 points and a plus-10 rating across 45 appearances with the minor-league squad in 2025-26.

Schmidt (illness) is expected to be an option for Tuesday's home matchup against the Oilers, per Cole Bagley of KSL Sports.

Head coach Andre Tourigny said Tuesday that there will be no changes to Utah's lineup against Edmonton, which indicates that Schmidt will be available after being unable to finish Sunday's game against the Kings due to an illness. The 34-year-old blueliner has chipped in just one goal and one assist across his last 22 appearances.

Shea (upper body) is expected to be available for Tuesday's home game versus the Avalanche, Josh Yohe of The Athletic reports.

Yohe noted that Shea has a significant gash above his upper lip and will play with a full cage Tuesday. The 29-year-old defenseman sat out Sunday's 5-1 loss to Carolina due to his injury. Ryan Graves is set to serve as a healthy scratch as a result of Shea's expected return to the lineup against Colorado.

Mackey was assigned to AHL Hartford on Tuesday.

During his latest stint with the Rangers, Mackey earned two shots on goal, two blocked shots, two hits and four PIM in three games. He has five goals and 15 points in 52 AHL appearances this season.

Samuelsson (illness) was absent from Tuesday's practice, Rachel Lenzi of The Buffalo News reports.

Samuelsson still could be available for Wednesday's game against Boston. He has accumulated 12 goals, 39 points, 97 shots on net, 137 blocked shots and 110 hits across 68 appearances this season. If Samuelsson can't play versus the Bruins, Luke Schenn or Michael Kesselring could draw into the lineup.

Pulock (lower body) won't be in the lineup against Chicago on Tuesday, per Stefen Rosner of NHL.com.

Pulock was on the ice briefly before the team's morning skate and will miss his second straight game. He has compiled three goals, 22 assists, 80 shots on net and 125 blocked shots across 67 appearances this season. Adam Boqvist will remain in Tuesday's lineup due to Pulock's absence.

Gostisbehere (lower body) won't play against Montreal on Tuesday, according to Patrick Friolet of RDS.

Gostisbehere will miss his ninth straight game, and it remains unclear when he will be available to return. He has generated 11 goals, 43 points, 98 shots on net and 50 blocked shots across 45 appearances this season.

Rielly (lower body) will be back in the lineup against Boston on Tuesday, per Luke Fox of Sportsnet.

After sitting out Saturday's 5-2 loss to Ottawa, Rielly will return to a top-four role and should see time on the power play against the Bruins on Tuesday. He has accounted for nine goals, 33 points, 125 shots on net and 96 blocked shots across 67 appearances this campaign.

Yakemchuk was recalled from AHL Belleville on Tuesday.

Thomas Chabot (right arm) and Lassi Thomson (lower body) were injured in Monday's 2-1 win over the Rangers, which necessitated Yakemchuk as well as Jorian Donovan being brought up from the minors. The 20-year-old Yakemchuk has yet to make his NHL debut but was the No. 7 overall pick in 2024. With Belleville this season, the right-shot blueliner has accounted for 10 goals, 36 points and a minus-30 rating over 50 appearances.

Head coach Travis Green stated after Monday's 2-1 win over the Rangers that Thomson (lower body) will be out for a while, according to Julian McKenzie of The Athletic.

Making his first appearance in the NHL since the 2022-23 campaign, Thomson logged two shots in just 4:25 of ice time before being unable to finish Monday's contest. Thomas Chabot (right arm) is also set for an absence, leaving the Senators extremely shorthanded ahead of a crucial divisional matchup in Detroit on Tuesday. Green said that two defensemen will be elevated from Ottawa's minor-league affiliate ahead of the team's second half of a back-to-back.
