Club chief of football Donald McDonald said both players had been cleared of any serious complaints and could line up against Essendon next Sunday at Docklands.
"There weren't any other real injuries. There were a few blokes that copped severe knocks but even then, they've all just pulled up sore," McDonald said.
"It was a very tough, physical game, there's no doubt about that. Our only real concern out of it was Hale.
"There's no one from the weekend that is definitely going to miss a week as a result of Sunday's game."
Hale dramatically left the field after colliding with teammate Lachie Hansen's hip in a marking contest in the second quarter.
He was knocked unconscious and play was halted as he left the arena on the medicart, wearing a neck brace. He was taken straight to Epworth Hospital for observation but released two hours after the end of the game.
McDonald said the Kangaroos would wait and see how he recovered from the heavy knock before making a call on his availability for round four.
"He's been cleared of any neck or serious injury. At this stage, it's just concussion," he said.
"Whether the concussion was severe enough for him to miss, we'll just have to wait and see how he responds in the next 24 hours."
Harding sent a massive scare through the Kangaroos when he went down late in the game with what appeared to be another knee injury.
The 27-year-old ruptured his anterior cruciate ligament at the Roos' final training session of 2006 and missed the entire next season.
McDonald said while there was initial concern when Harding collapsed in the centre circle on Sunday clutching the same knee, he had since been cleared of any further injury to the reconstructed ligament.
"We'll just see how he settles over the next 24 hours. He's walking around and we've ruled out any serious damage to him”, he said.
"It was scary for all of us because we know how hard he's worked and how well he's been playing this year."
