Jamie Elliott went down with a suspected serious knee injury in a horror finish as Collingwood marked Scott Pendlebury's record-breaking AFL appearance with a tense 10-point win over West Coast.
Magpies forward Elliott kicked three crucial goals in his side's 13.14 (92) to 12.10 (82) victory at the MCG on Saturday.
But he landed awkwardly on his left knee late in the final quarter and crumpled to the turf in pain as trainers quickly called for a stretcher to take the 33-year-old off the field.
Elliott departed amid a melee as Collingwood players seemingly took exception to something that was said by one of their opponents.
Captain Darcy Moore (hamstring) and young forward Will Hayes (shoulder) were also casualties as the Magpies (5-5-1) climbed into a "wildcard'' spot with their first win since Anzac Day.
