Cameron out with broken toe
The 30-year-old Scot broke his toe during Saturday's trip to Watford and a visit to a specialist on Monday confirmed the injury.
Cameron faces up to six weeks on the sidelines as he tries to recover from his latest setback, having just overcome an injury to his knee.
On the latest injury to Cameron, Wolves boss Dave Jones told the club's official website: "We are all disappointed for Colin, especially as he has only recently comeback from his knee injury.
"But these things happen in football. There's nothing we can do about it but get on with things and work at keeping Colin fit whilst the break heals."
