MELBOURNE Victory goalkeeper Danny Vukovic would do anything to be subbed in and take the place of his baby boy, who is facing his toughest opponent yet.

Eight-month-old Harley needs a new liver. And he won’t get it until his condition has deteriorated so much that this organ donation gift will truly be lifesaving.

Harley has biliary atresia, a condition which blocks bile ducts and causes liver damage.

Vukovic and wife Kristy gave their jaundiced baby to surgeons at the Royal Children’s Hospital for the first-line treatment, called a Kasai procedure, when Harley was just six weeks old.

Surgeons removed Harley’s damaged bile ducts, and replaced them with a section of intestine so bile could flow straight to the small intestine. One-third of children who have this procedure have no more liver problems.

But just before Christmas, the couple were told the procedure was not successful and Harley’s scarred liver would continue to fail.

Vukovic visited the RCH last week with his Victory teammates, a visit he has made to children’s hospitals all around the country, but now with added meaning.

The club has set up the Victoria For The Kids campaign to raise money for the RCH.

Vukovic and his teammates will be part of the Kids Day Out on Good Friday at the Melbourne Convention and Exhibition Centre.
