Wasps fly-half Jimmy Gopperth has been ruled out for up to nine months after undergoing knee surgery.

Gopperth will miss the majority of the upcoming season following a reconstruction of his anterior cruciate ligament.

The prolific 35-year-old did the damage in a pre-season thrashing of Connacht and will be sidelined for at least six months.

A short update on the Premiership club's website stated: "Jimmy Gopperth: Has undergone an ACL reconstruction following an injury sustained in Connacht.

"Estimated absence - six to nine months."

Wasps will be relying on new recruits Lima Sopoaga and Billy Searle to stay fit after Danny Cipriani's switch to Gloucester.

Prop Jake Cooper-Woolley is unavailable for between six and eight weeks following surgery on a ruptured bicep.
