The Islanders can take some encouragement from Anthony Duclair’s timeline, but they’ll still be without him until at least mid-November.

The team announced that Duclair will be out four to six weeks with a lower-body injury after the winger went down late in Saturday’s win over the Canadiens.

Duclair did not put weight on his right leg after getting up and appeared to be holding his groin.

After Lou Lamoriello initially told reporters that it was expected to be “long term,” four to six weeks feels like the Islanders got off relatively easy. Nevertheless, that is still a long time to be without a player who completes their top line, especially when the Islanders have struggled to score lately.

“I think that’s probably good news,” Ryan Pulock told The Post. “Obviously, him coming here and the skill and offensive touch he has, we’re gonna miss that here for the next, hopefully, four or so weeks. Obviously, gonna be a big boost to our team when he’s healthy and back. Obviously, could’ve been worse and we’re happy that he’ll be back here before we know it.”

The Islanders have not moved Duclair to long-term injured reserve — which would require he miss a minimum of 10 games and 24 days — and it’s not clear whether they will do so. Though Duclair is likely to miss the minimum amount of time anyway and it would help the Islanders in the short term — allowing them the cap space to call up Pierre Engvall and another extra forward — that would also stop them from being able to accrue salary-cap space, with every dollar of accrual counting between now and the March trade deadline.

For the time being, the Islanders have just 12 healthy forwards on their roster — a dangerous game but one they seem willing to play for the time being.

“I’m all good,” coach Patrick Roy said of his comfort level without an extra forward. “No problem with that. Actually, it never crossed my mind, to be honest. Right now, it is who we have. I’m comfortable with the guys we have. I like our lineup.”

The lineup Roy rolled out in the first game without Duclair turned out to have the same issue as the lineups he was using before Duclair got hurt: It struggled to score, losing a 1-0 game to the Red Wings on Tuesday — the third time in six games the Islanders have been shut out.

Roy did not switch up his top six ahead of Friday’s match in New Jersey, choosing to stick with Simon Holmstrom in Duclair’s usual spot on the top line alongside Mat Barzal and Bo Horvat.

“When you lose a player, it gives opportunities for others,” Roy said. “Simon, I thought he had a good game. We watched a couple clips together today just to continue to help him and continue to feel good with Bo and Barzy. But I liked the way he played.”

While the Islanders have controlled the puck for decent portions of time, that has not translated into anywhere near enough high-danger chances. Roy said after the loss to the Red Wings that the Islanders were not taking the goalies’ eyes away often enough, and that lack of net presence was noticeable Tuesday.

“I think it’s a bit of a mindset,” Pulock said. “A mindset of getting to the net, getting open for each other, trying to find ways to create more dangerous chances. As a D-man, I think we gotta continue with our movement, but I think there’s times we can get more pucks towards the net and get some of our forwards to go for tips or rebounds. After that, I think it’s just bearing down and finishing.”

Easier said than done.

“Put more traffic around the net,” Jean-Gabriel Pageau told The Post. “Goalies are good when they see the puck, so try and put a lot of traffic and maybe put that extra jam to put it in the back of the net. Sometimes that’s it. Maybe it goes with confidence, too. When you score a couple of them, your confidence spikes right back up.”
