Halford has joined Pompey on a one-month emergency loan and made his debut against Millwall on Tuesday night.
“He was out of my plans in the summer but he did well and got himself my squad of 25,” Wolves boss Mick McCarthy told the club’s official website.
“He came back with the intention of doing it and got into the 25 but is out of the team and he needs to play some games.
“This is a good opportunity for him.”
