The Wales international`s stay at Ashton Gate has been plagued by injury.
Vokes suffered a hamstring tear on his debut in a 3-0 home defeat to Millwall on the opening day of the season. He recently tried to make a comeback for the club`s reserves but suffered a setback and has now returned to Molineux with his five-month stint over.
City boss Keith Millen said: "Hopefully Sam will overcome his hamstring problem soon. I`ll keep an eye on his progress back at Wolves. He`s had such rough luck during his time here and I wish him well with his recovery."
