Wolves are set to send midfielder Adlene Guedioura to see a specialist to assess the extent of his ankle injury.
The 25-year-old sustained the knock while representing Algeria in an African Nations Cup qualifier in June.
This complaint has forced him to miss Wolves' three pre-season games against Crewe, Walsall and Notts County.
Guedioura missed six months of the previous campaign with a broken leg and will be keen to make an impact in the Wolves midfield this term.
"Adlene is seeing a specialist about his ankle," said boss Mick McCarthy. "We hope it is not too serious."
Dave Edwards, though, is making encouraging progress from a back injury that cut short last season.
He too has not played in any of the warm-up games for Wolves, but is nearing full fitness.
Wales international Sam Vokes picked up an injury against Crewe, which kept him side-lined for the next two games.
However, he is expected to return to fitness for the game against Ipswich on Saturday.
Meanwhile, Carl Ikeme has cast off his injury concerns and looks set to battle it out with Wayne Hennessey and new-boy Dorus De Vries for the first-choice goalkeeper slot.
Ikeme was in impressive form against Notts County in the 1-1 draw on Saturday and his return to form and fitness has given McCarthy a pleasing selection poser.
"He will be one of three in contention," McCarthy added on the club's official website.
"I have a great respect for Carl and his abilities. I put him in the team in our promotion season and kept him in the team."
