Iwelumo damaged the metatarsal he fractured during Wolverhampton's pre-season tour to Australia.

The Scotland international started his first Barclays Premier League match of the new campaign against Stoke City last weekend and impressed during the 2-2 draw.

But Iwelumo suffered the setback after Stoke goalkeeper Thomas Sorensen and Wolves central defender Christophe Berra landed on his foot.

"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."
