Patrick Ambrose will miss a further six weeks after aggravating a quad injury on the weekend.
After expecting to return this past weekend against GWS, Ambrose felt some discomfort in the lead up to the game which has resulted in fresh bleeding in his quad.
“We were in our last training session before he was due to return to play,” High Performance Manager Justin Crow said.
“He was punching a ball and felt his quad again.
“There is really no option now but to take our medicine and take another six weeks to get that right.
“It’s disappointing news for Paddy – there is a bit of a fresh blood in the quad, so we’ll re-load him and build him back up from here."
Young midfielder Darcy Parish will miss a second successive week with calf tightness, with the club's bye allowing him to have an extra week off before returning.
“Darcy’s calf tightened up during our main training session,” Crow said.
“We scanned that and what it turns out to be is a tibialis posterior injury, so that’s a smaller muscle in your calf complex.
“It’s a much better result than straining the other muscles in your calf, so we expect to have Darcy back the game after the break.”
Veteran James Kelly is expected to return this week against Port Adelaide after overcoming groin soreness last week.
“He’s much better for having the week off and he’ll do all of training and we’ll expect him to play.”
