Wolves weren't sure of the extent of the injury, which he picked up in the draw at Watford, but their fears were confirmed after the Scotsman had an x-ray.
Cameron, who is Wolves second leading scorer this season, has only just come back from a knee injury, but Wolves boss Dave Jones reassured fans this injury was not as serious.
"We are all dissapointed for Colin, especially as he has only recently come back, but it's not as serious as his knee."
The Scot will be missed, as Wolves are unbeaten in all the games (seven) he has played this season, winning five and drawing two.
So Wolves go in to tomorrow's game against top of the table Portsmouth, without one of their best players.
It will be tough but I think at home we shouldn't lose, even if they are top.
We'll have to wait and see. C'mon Wolves!!!!
