Jeremy McGovern has been ruled out of this Sunday’s clash with Fremantle after re-injuring his hamstring during the Hawks game last weekend.
The defender had been returning from two weeks on the sidelines, having initially injured his hamstring in round 16 against Collingwood, but left the field late in the game on Saturday with tightness in the same area.
Football manager Craig Vozzo said McGovern will miss at least two weeks.

"It was a bit disappointing that he didn't get through the game with the hamstring on the weekend,” Vozzo told Eagle Eye TV.
“The scan shows that it's just the same type of injury, nothing worse than that, which means he's probably going to be out for at least two weeks through the rehab phase.
“He's keen to fast-track things, but we'll just take it one week at a time.”
Vozzo said he was confident that Callum Sinclair would be available to take his place in the team against the Dockers after withdrawing from the Hawthorn clash with concerns over his knee.
“Callum was just not quite right,” Vozzo said.
“We needed another couple of days last week to get him right for the game.
‘He's tracking well this week. He's got full flexion in the knee joint now and hopefully he'll get through training later in the week and be available.”
In some positive news for season 2016, Vozzo reported that both Eric Mackenzie and Mitch Brown were progressing well after undergoing knee reconstructions early in the season.
Mackenzie and Brown both ruptured their ACL joints before round one was complete, but they are responding well to their rehabilitation programs and are now running.
“Eric and Browny, it's almost like a package deal there,” Vozzo said.
“They're doing a lot of things together.
“Browny's slightly less advanced than Ezy, just through the nature of time in terms of the rehab program, but they're tracking really, really well.
“They’re back on the oval and running now and looking better and better as the weeks go by.
“So nothing to suggest that we're not going to have them somewhere near full training by later this year, early next year.”
