SCANS have confirmed Fremantle wingman Brad Hill has suffered a calf tear, placing him in doubt for the start of the AFL season.

Hill suffered the injury at training on Wednesday, with subsequent scans revealing a grade one tear in his right leg.

The injury rules him out of Sunday's JLT Community Series clash with West Coast in Joondalup.

Hill faces a battle to be fit for the start of Fremantle's AFL campaign against Port Adelaide at Adelaide Oval on March 24.

His brother Stephen Hill (calf) will also miss Sunday's clash with West Coast but is expected to be available for round one.
