Collingwood’s wretched run with injuries this pre-season has continued, with ruckman Brodie Grundy the latest player under an injury cloud.

The Pies’ big man left the training track early on Tuesday afternoon, before leaving the club shortly after with his calf strapped.

Grundy will undergo scans to determine theĀ full extent of the injury.

New recruit Daniel Wells is highly unlikely to line up for the Pies in round one, while forward Jamie Elliott is battling an ankle injury and is also in doubt for round one.
