Collingwood forward Will Hoskin-Elliott looks proppy after injuring his knee during the Pies' clash with the Bombers at the MCG due to a knee injury.

Hoskin-Elliott suffered a heavy knock to the inside of his knee in the first quarter and immediately hobbled off the field and went down to the rooms.

The ex-Giant has been the Pies' leading goal kicker this season, booting 30 majors to sit eighth in the competition.

Hoskin-Elliott returned in the second quarter but looked sore. The Pies just can't seem to get a good run at it on the injury front, most recently losing Lynden Dunn (ACL) and Adam Treloar (both hamstrings) in the past couple of weeks.
