North Melbourne wingman Bailey Scott has encountered an obstacle in his pre-season preparations, reportedly sidelined with a calf injury.

Scott was reportedly absent from the Kangaroos' training session at Arden Street on Friday, having suffered a strain following an incident on Monday.

According to AFL Media's Josh Gabelich, scans confirmed low-grade damage to Scott's calf.

As a result, the 23-year-old isn't expected to participate in North's scheduled intraclub hitout next Thursday, though there is optimism he could appear in the Roos' pre-season clash with Collingwood on February 21.

Scott, a reliable contributor at Arden Street over the course of recent seasons, has registered consecutive third-place finishes in the Syd Barker Medal.

There was also concern for small forward Paul Curtis, who 'tweaked' his ankle, though he is expected to participate in the club's upcoming match practice.

Assistant coach Xavier Clarke was optimistic about Curtis' mishap.

"I think he's fine, I think it's just a little tweak of the ankle," Clarke told media on Friday.

"We've got an intraclub next Thursday and by all reports, he's going to be fine for that."

In other North Melbourne injury news, Tristan Xerri made a recovery from facial surgery last month and trained on Friday, while fellow ruckman Hamish Free suffered a concussion during the same session and will be placed in the league's protocols.

The Kangaroos have a second practice game scheduled with St Kilda before travelling to Sydney to play GWS in Round 1 on March 16.
