Eddie Howe’s side host the Toffees at St James’ Park knowing a win will guarantee Champions League qualification. Anything less will force them to rely on results elsewhere.
Isak missed last weekend’s 1-0 defeat at Arsenal due to a groin issue.
Providing an update at his pre-match press conference, Howe said: “He is doing okay. He hasn't trained with us yet but he's made good progress through the week. The next couple of days will be absolutely crucial to his availability on Sunday.
“There's a chance. It's difficult to give any more than that really. Until he trains with us we won't fully know how he's going to respond to the training and the demands that the game will place upon him.
“We'll only play him if he's fit to contribute. But at the moment he has an opportunity potentially.
“I think we'll leave it till tomorrow. But obviously this week he's been training just individually and building up his load. So he's been running and feels okay at the moment.
“But of course running is one thing and kicking a ball and doing all the other things that you need to do is another. So, so far what he's been asked to do, he's done it pain-free and he's done it well. So the next two days will be absolutely crucial.”
Will Isak start? Will Howe make changes? Here’s how Newcastle United are predicted to line-up against Everton.
