VIDEO: Callan Ward knocked out

GWS co-captain Callan Ward has been knocked out and may not take any further part in the preliminary final against the Western Bulldogs after a copping a brutal knee to the head.

The knock left Ward lying face down for several minutes, before trainers eventually helped him to his feet and from the ground, looking very groggy.
