COLLINGWOOD'S injury epidemic has become a crisis with superstar Jordan De Goey to be sidelined for at least one game with a low-grade hamstring strain.
The Magpies will also be without top draftee Isaac Quaynor after the four-game defender sustained a foot stress injury in the loss to Richmond on Friday night.
The club said both players would be sidelined for about the next 10 days before being assessed.
At the very least the pair will miss the Pies' clash with bottom side Gold Coast at the MCG on Sunday – a clash that was once perceived as a percentage-boosting opportunity for the Pies but now suddenly looms as a danger game for a team that has slipped from second to sixth in the past fortnight.
"Jordan played out the match against Richmond but reported minor hamstring soreness afterwards and a scan has revealed a low grade strain that will put him into rehabilitation for 10 days or so," Collingwood football chief Geoff Walsh said.
"Isaac suffered a stress reaction and will have his foot in a protective boot for the next 10 days or so. He will then be reassessed.
"We'll look at both boys then and make calls as to their immediate prospects."
FULL INJURY LIST Who's ruled out and who's a test?
The brilliant De Goey, 23, was Collingwood's leading goalkicker last year with 48 from 21 games, and again heads the club tally this season with 33 majors from 15 appearances, goaling in each of his past 19 games.
In recent weeks De Goey has spent increasing time in the midfield to provide some spark and speed to a group that has appeared one-paced.
In the 32-point defeat to the Tigers he was the Pies' best player with 28 possessions (10 contested), six clearances, 11 inside 50s, 1.3 and a goal assist in 80 per cent game time.
Quaynor has been impressive with his dash across half-back against quality opposition since making his debut against Hawthorn in round 16. He had 12 touches in 73 per cent game time against Richmond.
In better news for the Magpies star midfielder Dayne Beams will return to training on Monday after taking a month-long break to focus on his mental health issues.
It remains unclear whether Beams will play again this season as he also recovers from hip surgery.
Collingwood's casualty list might well have reached a critical mass.
Gun midfielder Taylor Adams was a late withdrawal on Friday night with a hamstring issue after Brayden Sier (calf) and James Aish (shoulder) were also sidelined after suffering injuries in the round 18 loss to Greater Western Sydney.
The Magpies are also without defensive trio Darcy Moore (hamstring), Levi Greenwood (hamstring) and John Noble (calf), and the season could be over for veterans Ben Reid (hamstring) and Daniel Wells (knee), while backmen Tom Langdon and Lynden Dunn have already been ruled out.
Star youngster Jaidyn Stephenson is serving a 12-week betting-related suspension that will sideline him until the end of the minor rounds.
