England manager Martin Johnson has confirmed that centre Riki Flutey will undergo exploratory shoulder surgery on Monday.
Flutey, who has had a shoulder problem since the British and Irish Lions tour of South Africa earlier this summer, could now emerge as a major doubt for England's autumn Tests that include a Twickenham appointment with New Zealand.
The arthroscopy procedure will give a clearer picture of whether or not Flutey has suffered serious damage to his left shoulder.
He joined French club Brive from Wasps in time for the new Top 14 campaign, but the injury has stalled his progress.
Flutey played a starring role in the Lions' third Test victory over South Africa in early July, and is an integral part of Johnson's England plans this season.
