Kyle Palmieri has yet to be seen in training camp and it is not clear whether he will be on the ice when the Islanders open the regular season on Oct. 14 against the Sabres.

“It’s hard to say,” coach Lane Lambert said of Palmieri’s status for the opener. “I don’t know that I could answer that question today. He’s skating. And so he’s day-to-day right now and we’ll just wait to see what happens.”

The Islanders, who scored a 2-1 preseason win over the Sabres, have called Palmieri day-to-day since the start of camp, when they said his absence was due to a knock suffered during an informal, pre-camp skate.

The day-to-day designation, though, is relatively meaningless given the Islanders used it last year for injuries in which players were out for weeks at a time.

Lambert on Wednesday declined to say whether Palmieri is dealing with an upper- or lower-body injury.

Palmieri missed 27 games last season with what was presumed to be concussions, as he took a hit from Morgan Reilly on Nov. 21, then another from Nick Ritchie upon his Dec. 16 return to the lineup.

He has not played a full season since being traded to the Islanders, missing 13 games in 2021-22 as well.

Being without Palmieri, who scored 16 goals with 17 assists last season, would be an early blow to a team that does not have much offensive firepower to begin with.

The second line of Pierre Engvall, Brock Nelson and Palmieri was the Isles’ best towards the end of last season.

There is plenty of time between now and opening night. But the lack of definitive answer is not a good sign.

Alexander Romanov (shoulder surgery) was held out of the Islanders’ first two preseason games, but has been a full participant in intrasquad scrimmages during camp.

Lambert left it an open question as to whether Romanov will play on Friday at home against the Rangers, but said, “he’s getting into that area where he could be getting close.”

Romanov, for his part, seems ready and eager to get going.

“No issues, no pain,” he said Tuesday. “Everything’s good.”

Isaiah George (maintenance) did not practice Wednesday. He returned to Tuesday’s game after missing a chunk of the first period following a big hit courtesy of Rangers forward Matt Rempe.

Sebastian Aho skated to Ryan Pulock’s left — where George has been for most of camp — during the scrimmage. (Adam Pelech, Pulock’s usual partner on the top pair, played in the preseason match against the Flyers).

In his first game action following a knee injury that took him out of the last four months of last season, Oliver Wahlstrom skated for 17:20 against the Flyers, the lone snag being a boarding penalty, which he called a timing misjudgment on his part.

“I felt great,” Wahlstrom said. “Obviously towards the end, the lungs, you just gotta keep playing more games. But I couldn’t have put in a better nine months in my life. It prepared me really well for this preseason.”
