"Now is the right time to call it a day," the much-travelled former Norwich City favourite told BBC Radio Norfolk.
"I've decided that, at nearly 34, with a dodgy hip, it wasn't worth continuing and not playing as well as I could."
It is only 15 months since Huckerby was let go by Norwich, who were then relegated to League One in their first season without him. And Canaries fans had hoped he might one day return after proving a big success in the States.
But San Jose announced at the weekend that his season is over because of surgery, thereby curtailing his contract. And he has decided to pack in while he is still on top of his game.
"The surgeon was happy enough that I could carry on and get to a decent standard," said Huckerby.
"But my game has always been about running past people and, as soon as I can't do that, I knew I was in a bit of trouble."
