Payne Haas cops ankle scare at NSW Origin training

Blues officials moved quickly to assure gathered media the treatment was only precautionary, with Haas not in any doubt for Wednesday's series opener. 

They were also confident Haas would be able to resume training when the Blues regather on Sunday after breaking for the weekend.

"It's precautionary," Blues advisor Greg Alexander said. 

"It's an ankle sprain. He just trod on the boot of someone as he was running backwards and he's just gone over on the ankle. 

"He'll be right Sunday. He'll train on Sunday. 

"There's not a history. It's just an ankle sprain that needs icing at the moment."

Any concerns over Haas' fitness would be a serious concern for the Blues, given his ability to play big minutes through the middle of the field.

NSW desperately needed the front-rower in last year's decider which he missed with a shoulder injury as the Blues went down 22-12 at Suncorp Stadium.
