A combination of illness and a proposed loan switch to Nottingham Forest meant that the winger has not been involved in recent weeks.
However, with Sako having made a full recovery and the chance of a move to the City Ground over for now, Jackett has insisted that the 25-year-old is in the right frame of mind to feature for Wolves.
"Yes, Sako will be involved at the weekend. He needs to get back to playing. He looked sharp in training. He's certainly fully focused and looking forward to this run of games," the Express & Star quotes Jackett as saying.
"He says he wants to put the Nottingham Forest episode behind him. Whether it resurfaces again, who knows? But if it does, it will be from their end.
"He's of a mindset now that he's going to concentrate on Wolves and if anything happens now, it will happen off his own good play. Those are his words, not mine."
Forest have been tipped to return with another bid for Sako during the January transfer window.
