Collingwood are awaiting tests on Darcy Moore and Kayle Kirby, while Tim Broomhead will undergo surgery after a disastrous day for the club.
Broomhead suffered a badly broken leg in the first quarter of the Pies’ 16-point loss to Greater Western Sydney at the MCG on Saturday and was taken to Epworth Hospital.
Kirby was taken to the same hospital after he collapsed during a VFL practice match being played at the club’s nearby headquarters.
Coach Nathan Buckley reported Kirby had suffered “some form of irregularity in his heartbeat” but was in a stable condition.
Moore didn’t reappear after halftime in the brave loss to the Giants and is in serious doubt for Friday night’s clash against traditional rivals Carlton.
“Darce was tight in a hammy and when it cooled down at halftime it wasn’t right to continue,” Buckley said after the match.
“We’ll assess that when the dust settles, but when you don’t finish a game you’re in some doubt aren’t you?”
Kirby remained under observation in hospital on Saturday night after the scary incident.
“It wasn’t a contact injury, the details are still coming to light,” Buckley said.
“He is at the hospital now and is apparently stable.
“I think the game was stopped for 40 minutes, so it was relatively serious.
“Talking to the doc, that was all the information they had, that he is going ok at the moment.”
Broomhead will face anywhere up to a year on the sidelines after suffering the sickening injury.
He threw his left leg at a loose ball as it bounced toward the goal line in an effort to kick a goal but instead collided heavily with the goalpost.
The 24-year-old smacked the turf in pain then remained prone face down on the turf behind the goal as his teammates celebrated before the gravity of his injury became apparent.
“He’s got a clean break of both the tibia and the fibula up high,” Buckley said.
“He’ll have surgery (on Sunday) … it’s terrible luck for a young bloke who is still trying to prove himself and make his way in the game.
“You don’t take the field thinking you’re going to walk off like that, but unfortunately its happened.
“Broomy is a well-loved, well-respected member of our footy club, so there’s no doubt it impacts.”
Broomhead was a late replacement for Ben Reid who was withdrawn from the team with a hip injury.
He is expected to be available to face the Blues.
