Toutai Kefu's Queensland career could be almost over after the captain was diagnosed with an injury that may sink the Reds' flagging Super 12 campaign.

Kefu will visit a specialist on Wednesday to learn whether he needs surgery on a fractured left eye socket suffered in the sloppy 34-6 loss to the Crusaders in Christchurch last Saturday.

The bullocking No.8 has already been ruled out for four weeks but surgery could sideline him for up to eight weeks in a massive blow for the Reds.

The worst-case scenario would force Kefu out until the penultimate Super 12 round, ruining his hopes of a glorious Queensland send-off before he links with a Japanese club next year.

Kefu insists the Reds can revive their season without him but sports bookmakers aren't convinced, winding Queensland out to 50-1 to win the Super 12.

The Reds are still hopeful attacking spark Chris Latham can recover from a knee injury in time for Saturday's must-win clash with the Chiefs in Hamilton.

Kefu will watch that match on television, returning home to Brisbane for further treatment.

"I'm in no pain but I've been told I could suffer permanent damage if I get another knock at the moment," Kefu said.

He was accidentally kneed by teammate Nathan Sharpe and cleared of any damage after X-rays yesterday, but a CAT scan revealed the extent of the injury.

Kefu's World Cup hopes are not in doubt, but he has lost his reputation as the unbreakable Super 12 forward.
