Essendon's much-vaunted new draftee Joe Daniher has had knee surgery, the AFL club has confirmed.
The Bombers say the 18-year-old forward, who joined the club under the father-son rule in the national draft, will be on a restricted training program in early January.
But the club says it was only minor surgery, and is not expected to cause much disruption to Daniher's otherwise impressive pre-season campaign.
"He's had a minor scope to clean up a bit of cartilage that came loose from his patella," Essendon football manager Danny Corcoran said on Thursday.
"We're expecting him to be running on day one when we return (from the club's Christmas break).
"He's had a good six weeks before the break. He's really trained very, very well so far in the pre-season."
