The 26-year-old former Queensland Reds forward was granted an early release from his contract by the Super 14 franchise.
He has moved back to Brisbane to manage the business previously run by this father but has not ruled out a return to rugby in future.
“Dad had a bit of a scare and it was clear that I needed to be at home and helping with the business, so that’s where I’m at,” Vedelago said.
“I was really looking forward to the 2008 season with the Force but family comes first, and the Force were fully appreciative of that.
“I had two wonderful years in Perth and hopefully, if I don the boots again down the track, I’ll get back there.”
Vedelago won 25 Super 12 caps with the Reds before moving to Western Australia in 2005 as an inaugural member of the Force.
Injury kept him out of most of the 2006 season but he played in all 13 games this year.
