Waratahs have revealed Kurtley Beale's knee injury is not as severe as first feared, but the Wasps-bound Australia international is still facing four to six months on the sidelines as he prepares for surgery on Monday.
A day on from his lucrative move to England's Premiership being confirmed, Beale was hurt in the first minute of Waratahs' Super Rugby victory over Bulls on Saturday after contesting a high ball.
While the 27-year-old appears certain to have played his last game for the Tahs, he could yet be available to Wasps early in the 2016-17 Premiership season - which begins in September - after scans led to a "better prognosis than expected".
A statement from Waratahs on Sunday read: "Beale is likely to be sidelined for four to six months, with scans revealing his patella tendon has torn from his patella.
"The result is the best possible prognosis given the tendon remains intact, requiring less invasive surgery, and that the injury is isolated with no other damage to the knee.
"Beale's length of time away from the game will be better understood following surgery tomorrow, Monday 16th May, at midday."
Wasps are reported to be making versatile back Beale, who has 60 caps for Australia, the highest-paid player in the Premiership.
