Youngster Josh Ward is set to miss at least a week after experiencing some soreness in his foot during training on Tuesday.

Hawthorn High Performance Manager Peter Burge said the injury is only expected to be a short-term issue. 

"Josh today reported some soreness in his foot during the middle of training and subsequently we sent him for scans," Burge said. 

"We've since got the results and he has got what we call a 'bone overload', there was a little bit of signal on his scans, but certainly nothing too significant.

"We've caught it very, very early and what that means is he won't play this weekend, but we're in a position where we can reassess next week.

"It's not a long-term injury by any means, more short-term."

Meanwhile, Emerson Jeka is also set to spend at least a month on the sidelines after he sustained a hamstring injury during Box Hill's game last weekend. 

"It's unfortunate given that he's just come back from a similar injury. But it's his other leg, not the same side as the most recent one," Burge added.

"He'll be back into a rehabilitation phase, at this stage we're not putting a timeline on it, but it would be no less than a month I would think."

In some positive news, second-year player Jai Serong is expected to return next round to be available for selection after being diagnosed with pericarditis.

"He's going fantastically well, he did full training today and the end of last week," Burge said.

"He has been doing some extra conditioning to progress quickly back into game play.

"If there was a VFL game this week, he would most likely be available."
