Wolves caretaker boss Steve Davis says Raul Jimenez has returned to training.
The Mexico international has recovered from a groin injury.
Davis said, "I watched him training.
"He's progressing well and it's good to see him moving around.
"He will be ready when he's ready."
On whether he will be back before the World Cup, he added: "That is the target. That was always the target."
Davis also said midfielder Matheus Nunes will be assessed tomorrow and it "could go either way."
