Australia fly-half Quade Cooper requires surgery on his injured shoulder and will miss the upcoming series against France as part of a four-month lay-off.
Cooper, a key player for the Wallabies, suffered the problem during Queensland’s defeat to Melbourne Rebels on Saturday.
He had MRI scans on the joint immediately after the game and will go under the knife as early as Tuesday, but will not recover in time for the end of the Super-15 season.
New Zealand-born Cooper, 26, will also undergo arthroscopic surgery to clean up loose cartilage in his hip at some point during his recovery period.
Wallabies coach Ewen McKenzie must now find a new No 10 in time for their first Test against France in Brisbane on June 7.
Queensland head coach Richard Graham anticipates Cooper will make a full comeback, as he did following knee surgery in 2012.
He said: “A player of Quade's ability rarely has extended breaks from the game, so if there is a silver lining to this injury layoff it is that this will allow him time to refresh and repair his body.”
“Quade is obviously disappointed to miss the rest of the season, but he knows these two operations will bring him back to full health.”
Cooper has 50 caps for Australia, scoring 124 points.
Brumbies fly-half Matt Toomua is the most likely replacement for the Aussies, with Kurtley Beale and Bernard Foley of the Waratahs the other possible contenders.
