According to the Herald Sun’s Sam Edmund, GWS co-captain Callan Ward is in “serious doubt” for Round 1.

Ward sustained a knee injury in GWS’ first JLT series clash against the Swans.

Edmund told SEN Breakfast that the signs aren’t looking good for the 28-year-old.

“Callan Ward, and we’re still fleshing out the details of this is in serious doubt for Round 1,” he said.

“He’s got a nasty knee injury.

“He was injured, we understood, in that JLT Series game against the Swans, but it slipped under the radar.

“He’s in Melbourne at the moment with a big knee brace, whether he’s seeing a specialist or been granted a bit of free time, we don’t know.

“I’ve been told by the Giants, it’s definitely not a ruptured ACL.”

The Giants are set to release a statement later today to reveal the full extent of the injury.
