The Panthers have revealed that Nathan Cleary's syndessmosis injury will not require surgery, however, he will miss the next month.

This comes after the NSW playmaker was struck down before half time in the Blues' series equalising win on Sunday in Perth. It rules him out of the Origin decider at ANZ Stadium in teo weeks time.

His diagnosis was described as a high grade lateral ankle injury as well as large-scale swelling. It comes as a blow for Penrith who sit one game outside of the eight with a chance to jump the Warriors this weekend.

Cleary said to The Sydney Morning Herald  "That's what dreams are made of, to play in game three of a decider - especially at ANZ.

"I was just icing last night and I couldn't get much sleep as it was throbbing... I've just got to get in recovery mode now" he claimed yesterday a day after the win.

Cleary would have been pleased with the Blues second half which saw them reverse the game one loss and comfortably beat the Maroons by 38-6. Despite not being able to play, he will be at ANZ to hopefully witness a back-to-back Origin crown for his Blues, who are re-writing their own history after a decade of misery in the contest.
