Maroons team doctor Matt Hislop found Mbye slumped on the floor at the team's Perth hotel on Friday morning after the Wests Tigers captain called him for help.

It is believed Mbye went into anaphylactic shock and his airways were closing before Hislop revived the 25-year-old with an anti-allergy injection EpiPen.

Asked if it was life threatening, Hodges said on Sunday: "I am not a doctor but he was in a bad way.

"But he will be ready to go, he was buzzing last night.

"It was a strange thing that happened to him. We are just glad that he's OK; he's got three little kids at home so his health is the most important thing.

"We are just lucky we have great medical staff here who looked after him."

Remarkably Mbye will run out for Queensland barely 48 hours after the frightening incident.

It will mark his second Origin game, after he made his debut in Queensland's 18-14 series opening victory.

"It was an accident, he wasn't aware he was allergic to something but he is not going to give up this opportunity (to play Origin)," Hodges said.

"You wait your whole life to play for Queensland."

Maroons officials said Mbye would undergo extensive tests when he returns to Sydney after game two.

A relieved Mbye admitted he was still scratching his head over the cause of the episode.

"I had a few things that morning. I had my brekky, I had my juice, it was a standard sort of day," he told the Nine Network.

"It was nothing out of the ordinary. I guess that is what is the worst bit; I don't know what it is yet."

Asked if he feared for his life, Mbye said: "Potentially, I am not quite sure how far it could have gone but, yeah potentially, he saved me.

"I'm glad I wasn't home, to be honest, my missus wouldn't know what to do."

Mbye completed the Maroons' captain's run on Saturday at Optus Stadium, giving no indication of the drama that had unfolded 24 hours earlier.
