Exeter and England back Jack Nowell has undergone ankle surgery after being injured in the Premiership final against Saracens earlier this month.
Chiefs rugby director Rob Baxter confirmed the operation was successful and said "at this stage we see no reason" why Nowell's World Cup hopes should be jeopardised.
Nowell, who had an outstanding game at Twickenham despite Exeter's defeat, went off midway through the second half after attempting to tackle Saracens wing Sean Maitland.
In a statement, Exeter said: "Nowell underwent initial scans on both his knee and ankle in the aftermath of the final.
"Since then, the Cornishman has been away on holiday with his family, after which he has returned to Exeter and underwent surgery on his ankle on Tuesday."
Baxter has not put a timescale on when he expects Nowell to be fully fit again, but offered a positive outlook.
"Jack's had an operation on his ankle," Baxter said.
"And at this stage we see no reason why it should jeopardise him being involved with England at the Rugby World Cup, nor with us heading into the new season."
England's opening World Cup warm-up game is against Wales on 11 August, and their first tournament match is an appointment with Tonga in Sapporo six weeks later.
