Martin, a forward, has three points (two goals, one assist) in seven games, including a goal and an assist in a 4-2 win against the Ottawa Senators at Canadian Tire Centre on Friday. He was helped off the ice in the second period after his left leg struck an open door on the Senators bench. He returned for the third, and Lamoriello initially said playing on the injury didn't make it worse.
"No … well, I can't answer that, I'm not a doctor," Lamoriello said. "But he's out right now."
Kuhnhackl left the game against Ottawa at 12:29 of the first period after sliding awkwardly into the boards while battling for the puck with Senators defenseman Dylan DeMelo. The forward had to be helped off the ice by his teammates.
The Islanders are also without forwards Leo Komarov (illness), Jordan Eberle (lower body) and Andrew Ladd (knee). Lamoriello said they will not call up a forward from Bridgeport of the American Hockey League ahead of the game against the Philadelphia Flyers at Nassau Coliseum on Sunday (7 p.m. ET; MSG+, NBCSP, NHL.TV).
New York (7-3-0) has won six in a row while outscoring its opponents 19-11.
"This is where people get an opportunity to step up and take advantage of that, which is what the game's all about," Lamoriello said.
Lamoriello said Komarov, who hasn't played since Oct. 17, is day to day. Eberle, who was injured Oct. 12, has resumed skating, but it's unknown when he can return.
Ladd, who was injured March 24, has been skating with the Islanders. Lamoriello said Ladd will see doctors "in a short period of time." He's expected to return in late November.
Oliver Wahlstrom, a healthy scratch Friday, will play Sunday. The 19-year-old forward was a first-round pick (No. 11) in the 2018 NHL Draft and does not have a point in four games. Forward Ross Johnston will also play against the Flyers.
"You never wish injury on anybody, but when a door opens, you either step in and join the party or you get kicked out for non-participation," Islanders coach Barry Trotz said.
Lamoriello said "no update" twice when asked about forward
Joshua Ho-Sang
, who requested a trade after being placed on waivers Sept. 30. Ho-Sang cleared waivers but was told not to report to Bridgeport while Lamoriello worked on a trade.
The 23-year-old was a first-round pick (No. 28) at the 2014 NHL Draft and has 24 points (seven goals, 17 assists) in 53 games with the Islanders.
