RUGBY league Immortal Graeme "Changa" Langlands was rushed to a Brisbane hospital last night after being knocked unconscious when he fell from a car in a motorcade at the World Cup final.

A spokesman for the Wesley Private Hospital refused to provide details on the former St George great, fuelling speculation about his condition.

Langlands is one of six remaining Immortals and had been invited to Brisbane to participate in a parade of the team of the century as the final celebration marking the 100th anniversary of the code.

NRL media manager John Brady said Langlands, 67, was put in a neck brace after regaining consciousness before the former Test fullback and centre was sent for precautionary scans accompanied by fellow Immortal Bob Fulton.

"He was sitting on the back of a utility vehicle and had just completed a lap of Suncorp Stadium as part of a motorcade featuring members of the team of the century named earlier this year," Mr Brady said.

"The vehicle had come to a stop and then, as it attempted to accelerate over a hump, [he] lost his balance and fell to the ground."

Fulton said last night his old friend and on-field rival had not been officially diagnosed.

The accident involving Langlands cast a pall over the game between Australia and New Zealand last night, which the Kiwis won 34-20 in a shock result.

Langlands shot to fame as a footballer and coach during the 1960s and 1970s. He represented Australia 45 times from 1963 to 1975 and captained his country in 15 Tests and World Cup games.

Langlands was the fullback and goalkicker for the St George Dragons in the latter half of their record run of 11 consecutive premierships from 1956 to 1966.
