North Melbourne spearhead Ben Brown is on track take on Hawthorn on Sunday and could be cleared to play as early as Thursday afternoon.

Brown was concussed in a Brodie Grundy tackle in North's loss to Collingwood on Saturday night and was assessed in hospital after the game.

North coach Brad Scott told reporters on Thursday the club's tests on Brown suggested he had recovered so well from his concussion that the Roos might be able to make a call on his fitness earlier than expected.

"He's carried on the rest of the week like he started the week. He's recovered remarkably well and feels good. All his measures and markers and all the testing that we do looks really good," Scott said ahead of North's training session.

"We said earlier in the week we would wait until the last minute but hopefully after today's training we'll have a clean bill of health and he should be right.

"Now all that's depending that he doesn't have anything unforeseen in the next couple of days, such as waking up with a headache or something along those lines, but at this stage it looks really positive." 

Brown started Thursday's session with North's forward group and took part in the early skills drills without any apparent restriction.

Scott stressed North's inability to play finals would have no bearing on Brown's selection, saying the forward would play if medically cleared.

Forward Kayne Turner will return this weekend at some level for his first game since injuring his posterior cruciate ligament in the round 13 loss to St Kilda.

Turner is "a really good chance" to come straight back into the Roos' senior team, according to Scott. But the Roos coach noted the forward's history of hamstring injuries, saying North would have to be satisfied he was sufficiently conditioned for AFL football.

Jy Simpkin (ankle) could also return against the Hawks after he was a late withdrawal from North's loss to Collingwood, but Scott said the first-year forward would have to prove his fitness in the Roos' remaining training sessions.

Majak Daw (foot, out since round 19), Mason Wood (calf, round 15) and Corey Wagner (ankle, round 17), however, will be sidelined again this weekend, with no clear timeframes on their returns.

"(Majak) will see a specialist later this week and hopefully we'll get a clearer diagnosis as to what it is. At this stage, we're treating it as something that is minor and potentially he'll be back and that's certainly our aim," Scott said.

"Mason has been a frustrating one because we thought it was a calf complaint that was only going to be a couple of weeks maximum and it's dragged out. It's still our intent to get him back but clearly we don't want to put him at risk and have a serious calf problem going forward.

"We're pushing all of our guys who are some chance to play to do everything they can and everything we can to get them up to play, and if we just miss we just miss.

"But my attitude is they'll be further advanced in their pre-season if they get their rehab right now."
