Australian hooker Cameron Smith has vowed to be fit for Origin I after suffering a suspected grade two medial ligament strain in his right elbow in Friday night's Test win over New Zealand.

Smith failed to see out the first half of the Kangaroos' 12-8 victory after hyper extending his elbow when he found his arm caught under the weight of Kiwi lock and Melbourne Storm teammate Adam Blair, and is now set to be sidelined for four weeks.

Writhing in pain on the ground, Smith initially attempted to have the arm strapped in an effort to get back on the field before Kangaroos medical officials ruled against a second half comeback.

He will undergo scans on Saturday and is a definite non-starter for Sunday's NRL clash against Brisbane, with Smith now eying a return in time to take his place in the Queensland No.9 jumper for Origin I on May 26.

But Smith will be touch and go for the clash with game one just three and a half weeks away.

"Absolutely," Smith said when asked about being right for Origin I.

"My aim is to be out here on Sunday against the Broncos but I don't know if that's going to happen.

"Certainly Origin's the thing that I'm going to be striving to be ready for now."

Smith had the arm in a sling in the dressing rooms after the game, admitting the wing was still painful.

"That was the feeling that I had, that I may have dislocated it, but it didn't stay out if it did," Smith said.

"I've been fairly lucky in my career, I haven't had too many injuries.

"I just got stuck underneath Adam Blair and I think he was just trying to turn over - there's only so far my arm can bend and it just kept going."
