Jake Gordon's hopes of retaining the Wallabies scrumhalf jersey ahead of the Rugby World Cup have been dealt a major setback, with the star No.9 ruled out weeks before the beginning of the Test season.
Gordon went down in the first half of the NSW Waratahs' 31-25 loss to the Western Force on Saturday after taking a quick tap and falling after a couple of steps.
Gordon looked gutted and in extreme pain as he was assessed by a medico, before being carried off the field by two trainers.
On Monday, the Waratahs confirmed that he had undergone a successful surgery on a torn Achilles.
"The scrumhalf will be sidelined for a significant period and will miss the Wallabies' upcoming Nations Championship campaign," the statement said.
