Taylor told Villa's official website: “As far as I’m aware it’ll be up to Portsmouth when his loan period ends.
“The thing with Steve, like everybody else in this financial climate, there are a number of players who can’t get their careers going.
“So when players do get an opportunity, we’d like to help them. It’s as simple as that.”
Stone missed last weekend's 3-0 victory over Stoke with a hamstring injury but it is not serious and he should be available for Pompey's trip to Sheffield Wednesday on Saturday.
