THE decision to use a stretcher to carry Port Adelaide's Jacob Surjan off late in the Power's upset win over West Coast is likely to be examined further after footage last night cast doubt on how impaired the defender was following a heavy clash.

The Eagles were finishing strongly against the Power at Subiaco late on Saturday night when play was stalled for several minutes to allow Surjan to be taken by stretcher from the field after he hit his head when laying a tackle on Brad Ebert.

Questions about the extent of the injury suffered by Surjan were raised when he rushed on to the field minutes later to celebrate the three-point win with his teammates. Port Adelaide's veteran forward Warren Tredrea was clearly shocked.

But it is down-the-ground footage shown during the Fox Sports coverage of the Western Bulldogs win over Richmond last night that raises concerns as to whether it was a tactical ploy by Port Adelaide to delay play. Click here to see the vision.

The footage shows Surjan regain his feet shortly after the heavy collision with Ebert and then walk about 10 metres towards the centre of the Eagles forward line before being approached by a Port runner.

As the Power's medical staff enter the playing field with a stretcher, the footage appears to show the trainer telling Surjan to lie back down on the ground.
