North Melbourne vice-captain Harry Sheezel says he is "shattered" for his good friend and teammate George Wardlaw, who suffered a hamstring injury during Wednesday's training session at Arden St Oval.

Wardlaw, who has earned two AFL Rising Star nominations from his first two seasons for the Kangaroos, hobbled off early in the session as the Roos took part in a high-intensity match simulation.

He left Arden St for scans on his right hamstring.

"We'll wrap our arms around him," Sheezel told reporters after the session.

"He's worked so hard on his body the last few years to get it right. 

"It'll be hard for him, but I know his professionalism and I have no doubt he'll keep working hard.

"He was so fit and firing and ready to go. Hopefully it won't be too long and he'll still be able to show that this year, but we're shattered for him."

Assistant coach Leigh Adams shared Sheezel's disappointment for Wardlaw.

"He'd done 90 per cent of the preseason and had been in some really good form," Adams said.

"His body was strong and fit and healthy, but unfortunately it looks like he's going to miss a bit of footy.

"One thing I do know about George, he's really resilient. He'll do his rehab really diligently and make sure that he gets himself nice and strong and fit and ready to go.

"With his mindset and resilience and professionalism, I'm sure he'll be out there, hopefully sooner rather than later."

Midfielder Tom Powell was among the standouts in the match simulation, which consisted of four 20-minute quarters followed by extra running drills in warm conditions at Arden St.

Powell, who has added bulk to his frame after being shortlisted for last year's 22under22 team, saw plenty of the ball to continue his eye-catching pre-season.

"I've been really impressed with the way Powell's gone about his footy," Adams said. "You can see he's put the size on. He's coming into his fifth season, and he's looking like he's really ready to take his game by the scruff of the neck."

Trade recruits Luke Parker and Caleb Daniel underlined the experience they will add to Alastair Clarkson's team this season, Parker patrolling in a defensive midfield role for much of the match sim, and Daniel providing a calm head with pinpoint distribution from half-back. 

Young guns Colby McKercher and Riley Hardeman were also clean with the ball, while newly-arrived forward Jacob Konstanty earned applause from the watching fans by finishing an early passage of play with a slick goal.

Adams said it was pleasing to see the Roos' game plan coming together ahead of Clarkson's third year as senior coach.

"We've had two years now of embedding our game plan the way we want to play, and now we're at that stage where we want to start to execute it out on the field for longer periods of time, and that's what we're starting to see out there today."
