A hamstring injury will keep star midfielder Luke Davies-Uniacke off the field for approximately the next month, while Jack Mahony's season has come to a premature end after damaging his shoulder in last Saturday's match.

Davies-Uniacke clutched at his left hamstring after accelerating out of a contest during the third quarter against Port Adelaide in Hobart.

"Luke's pretty sore just walking at the minute and is in low-level strength at this point," head of performance Kevin White told NMFC Media.

"We see a timeline of around 3-5 weeks (until a potential return).

"Jack is meeting with a surgeon today (Tuesday) to look at opinions on which surgery he'll get, and we'll have more information on his recovery process in the coming weeks."

A collision with Port's Jason Horne-Francis will see dynamic forward Cam Zurhaar (cheekbone) miss Saturday's Round 10 clash with the Swans.

Zurhaar has been a pivotal contributor for the Kangaroos so far this season off the back of his boost in midfield minutes.

"Cam had a bit of depression of one of the bones in his face and had a little surgical procedure (on Monday) just to pop that back up," White said.

"At the minute it'll be one week of non-contact for him and then he'll return to play."

Like Davies-Uniacke, recruit Darcy Tucker was dealt a hamstring blow in the hitout with the Power, but has pulled up favourably in comparison to his midfield counterpart.

"We're thinking one week, but he's presenting really well," White mentioned.

"He's a test, but a week off is likely for Darcy."

Young defender Flynn Perez is unavailable for selection after he suffered a delayed concussion at Blundstone Arena. He'll join Lachie Young in the AFL's 12-day concussion protocol after the backman also sustained a concussion, but during last Thursday's main training session.

"Flynn, just after half-time, reported some concussion symptoms, was taken down downstairs to go through the protocols and was effectively ruled out from there," White said.

Josh Goater had a player fall over his knee during the the first quarter of Saturday's reserve match-up against Frankston and is expected to miss the next 3-4 weeks.

"Scans revealed a moderate-grade MCL injury, but he's actually going really well at the moment," White said.

"He's in a knee brace this week and will come out of that next week."
