Wolves right-back Ronald Zubar will have a scan after limping out of the pre-season clash against Bohemians with an ankle injury.
The 24-year-old twisted his left ankle in the 20th minute of a game Mick McCarthy's side eventually won 3-0.
Zubar will miss Tuesday's friendly against Walsall but hopes to be fit enough to feature in Saturday's game at Charleroi.
He said: "A ball came across and I tried to turn but my ankle twisted and it gave me a bad feeling - it was painful. It's a little bit sore and swollen, so I'll keep the protective boot on it for a couple of days.
"I've had it treated over the weekend, I'll probably have it scanned today and we'll see what the problem is inside. Hopefully, if there's nothing wrong, I'll be back in training tomorrow.
"It was disappointing because it was the first game back and I want to prove myself, keep it going after last season. But we won and I played 20 minutes. Hopefully I'll be OK for next weekend."
