The 30-year-old is currently a free agent after being released by Boro at the end of August.
Despite the Sierra Leone international's arrival at Molineux, Jackett has refused to confirm whether the forward will be offered a contract.
"We will be talking to him and there will be some summing up afterwards as to where he is, but he's a free agent looking for a club and has been to us for two days, which was the original agreement," he told the club's official website.
"He's done okay, and from finding out about his overall situation, he would need a work permit because he's a Sierra Leone international."
Wolves continue their Championship campaign on Sunday when they travel to Reading.
