HAWTHORN young gun Jed Anderson will miss the club's training camp to South Africa next month and will have a delayed start to pre-season after contracting pneumonia.
Anderson is recovering from a "severe" case of pneumonia in a Darwin hospital.
The Hawks are unable to put a likely time frame on Anderson's recovery, but have been buoyed by his improvement in recent days.
"We expect him to make a full recovery, but it will take him a little while," Hawthorn football operations manager Chris Fagan said last night.
"He has lost some weight and lost some muscle mass and we will give him a bit of time to recover from that.
"The good thing is he is recovering now, I don't know whether it will affect his start to the season. There are a lot of unknowns at the moment."
Fagan said the club's medical staff was liaising with Darwin doctors, but there was still no clarity as to how the 19-year-old contracting the illness.
"We don't know how he got it, we have been trying to find that out, but it is not easy to ascertain," he said.
"If he is well enough to come back to Melbourne before Christmas, and do a bit of walking and building up, then we will get him back.
"He probably won't go to South Africa (on December 8). We are in the hands of our doctors."
Anderson, who played six games in his debut season with Hawthorn this year, including the qualifying final win over Sydney, is originally from the Northern Territory.
He narrowly missed selection in the club's AFL Grand Final side, but was a member of the Box Hill Hawks' VFL premiership side this year. He is expected to become a more regular senior player in 2014 and beyond.
