Wolves striker Chris Iwelumo will again be sidelined with the injury he suffered during the pre-season tour of Australia.
The Scotland international fractured a metatarsal in his foot during a tour match against the A-League's Perth Glory in the off-season and made his first start for the season on the weekend in Wolves' 2-2 with Stoke City.
"He has damaged the fracture site. He has not refractured the metatarsal so please don't go away and say 'It is broken' because he hasn't done that," said manager Mick McCarthy.
"He has unsettled it more than anything and he will be a few weeks out. It doesn't happen normally but Sorensen and Berra fell on him when he got his foot planted (in the ground).
"Where the actual fracture is and the metal screw goes in, it has been unsettled, disturbed, but not broken."
McCarthy added: "It is a big blow after all he has gone through. He played well last week at Stoke and to have him back was a real bonus.
"It is sad for him, the Stoke game was his first back in the Premier League and the Stoke game suited him, the physical nature of the game."
