North Melbourne has not ruled out concussion sufferers Shaun Higgins and Ed Vickers-Willis from playing against Port Adelaide on Saturday night, captain Jack Ziebell says.

Higgins and Vickers-Willis were involved in sickening collisions within seconds of each other in the third quarter of the Roos' celebrated 28-point defeat of Hawthorn on Sunday.

Vickers-Willis was able to run from the ground, whereas Higgins – whose wife Heidi gave birth to the couple's first child in the early hours of Sunday – was carried off on a stretcher and taken to Epworth hospital.

Ziebell said the six-day turnaround between matches was not in his teammates' favour, but that both would be in the selection mix if they passed concussion tests later this week.

"It was a big day for 'Higgo'. He welcomed his baby girl into the world early in the morning, didn't have too much sleep and was unfortunately carted off in the second half," Ziebell told reporters on Monday.

"He's going really well at the moment. He's been cleared of any neck damage; there's no neck fracture or anything like that.

"I think he needs to get a little bit of plastic surgery on his lip – I think he put his teeth through his lip – but other than that I think he's in good spirits and going pretty well."

Higgins retained the memory of his daughter Rosie Joan's birth despite his on-field incident and his teammates' jokes about him having twins, according to Ziebell.

"There's been a fair bit of contact (from his North teammates)," Ziebell said.

"He was laying low last night resting up and I think there might be a few visitors coming in today to make sure he's going OK.

"(But) I'm pretty sure he's keen to get back and see his wife and their daughter Rosie as well this afternoon."

Higgins' clash of heads with Ryan Burton, who made the split-second decision to bump rather than tackle the Roos' reigning club champion, has sparked discussion about the young Hawk's action.

But Ziebell, one of the stars of North's victory with two goals, said he would not be making any judgment.

"It's a tough one. I've been in that situation before, whether you choose to bump or tackle – it's a split-second decision," he said.

"It's a really tough one to make and I'm not going to sit here and judge anyone on that one act.

"Our priority is making sure that Higgo's all right and I'm here today to tell everyone that he's going really well."

Ziebell spoke to Vickers-Willis on Monday morning and reported he had "pulled up really well".
