It is the same knee he injured in 2015 during his last stint in rugby league at Penrith.

Idris returned to the NRL this season on a cut-price one-year deal with Wests following an 18-month sabbatical from the game which he spent travelling.

The 26-year-old is off-contract this year.

Idris has endured an injury-disrupted season, managing just five games this year.

He will meet with his surgeon on Friday and will be out of the game for a minimum six months.

Idris burst on the scene as an 18-year-old for Canterbury in 2008 while still in high school before stints at the Gold Coast and Penrith.

He played for NSW and Australia.
