COLLINGWOOD defender Tom Langdon will need scans to determine the extent of an ankle injury he suffered in the Magpies' loss to West Coast at Domain Stadium on Sunday.

Langdon initially appeared to clutch at his right knee after a third-quarter clash with Eagle Mark Hutchings, but the defender was then carried from the field by Collingwood trainers and received attention to his ankle.

He did not play any further part in the match and he had ice applied to his ankle in the last quarter.

"We'll know more once we get the full report from the docs, but he wasn't able to come back, clearly," Collingwood coach Nathan Buckley said post-match.

Ben Sinclair copped a knock to the chin the third quarter and had to go down to the rooms for a concussion test but Buckley said he passed.

"Sinclair obviously copped the elbow to the chin," Buckley said.

"We thought initially he would be out for the rest of the game. But his concussion test came back fine and we were able to get him back on for the last five or 10 (minutes), but I think he is feeling OK."

Buckley also revealed that skipper Scott Pendlebury nearly missed the Eagles clash through soreness but he fought on to collect 29 disposals.

The Magpies have another six-day break before facing Carlton in a must-win clash at the MCG next Saturday afternoon.
