Tarryn Thomas is expected to spend 4-8 weeks on the sidelines as a result of the injury he suffered against the Eagles on Sunday.
Thomas copped an accidental kick to his ribs as he attempted a smother at the end of the second quarter. He played no further part in the game.
General Manager of Football Performance Dan McPherson says Thomas’ timeline of recovery is difficult to assess at the moment.
"He’s got some internal bruising, but fortunately his ribs are fine, there’s no fracture. The ongoing advice and assessment from specialists will be the guiding factor as Tarryn recovers," McPherson told North Media.
"Tarryn’s health is our priority, so with that in mind we will take a conservative approach with his recovery and continue to monitor him closely."
Luke Davies-Uniacke will also miss this weekend's clash with Brisbane after it was confirmed he suffered a concussion during Sunday's game.
Davies-Uniacke suffered the injury in the first quarter of the clash after hitting his head on the ground following a tackle from West Coast's Willie Rioli, but is recovering well.
"He's in the 12-day protocols so unfortunately he'll miss this weekend," McPherson said.
"His symptoms have been pretty good since the weekend, so unless there are any hiccups we expect he'll play Round 4 against the Swans."
Ben McKay missed the clash with the Eagles with a concussion of his own, suffered in Round 1 against Hawthorn. He's firming for selection this weekend.
"He'll be fine, he's progressing really well so we expect he'll be good to go for Saturday night," McPherson said.
Jed Anderson could take to the field sooner than expected after increasing his training loads in recent weeks, with the midfielder expected to compete for a place in North's VFL side in the near future.
"He's back into full training, but we still need to increase his loads and his fitness base before he returns to play," McPherson said.
We’ll look to get him back to potentially play half a game in the VFL in the next couple of weeks."

Matt McGuinness is in line for his first competitive appearance of the season this weekend, with the key defender shaking off the foot injury that's seen him sidelined since late pre-season.
"He'll most probably play half a game in the VFL this week provided he gets through training with no issues tomorrow,” McPherson said.
"He’s going well. He's feeling good, his foot's good and he'll be back in this week."
Will Phillips' recovery from glandular fever is going well, with the midfielder looking to increase his training loads this week as he prepares to put his name up for selection as soon as possible.
McPherson says Phillips' loads will still be driven by his symptoms.
"He's starting to feel a lot better so he'll increase his training this week," he said.
"At the moment he's feeling good so we'll increase his loads this week and be guided by how he's feeling. Hopefully he'll be back within the next couple of weeks.”
