Patrick Ambrose will miss another six weeks after aggravating a quad injury.

The defender was expected to return against GWS last week but he felt some discomfort in the lead-up to the game.

“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 bleed in the quad, so we’ll re-load him and build him back up from here."

Darcy Parish will miss this Saturday’s match against Port Adelaide, but he’s expected to return against Sydney after the bye.

The midfielder hurt his calf in the lead up to the game against the Giants.

“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.”

James Kelly is likely to be available for the game against the Power this Saturday night.

The Club took a low risk approach after the 300 game player felt some minor discomfort in his groins last week.

“He had some low level groin issues, he’d had a history of that in the earlier part of his career,” Crow said.

“He’s much better for having the week off and he’ll do all of training and we’ll expect him to play.”

Mitch Brown has stepped up his rehabilitation program after injuring his ankle against Melbourne in round six.

He’s on track to be available for the match against Sydney. 

Jayden Laverde is aiming to return a week later against Brisbane after injuring his ankle in March.
