Exeter Chiefs winger Jack Nowell is to have knee surgery and will miss England's summer tour of New Zealand.
The 21-year-old, who started all five of England's games during this year's Six Nations, is expected to be fit for the start of the 2014-15 season.
Nowell's shoulder, which he injured against Leicester last month, will also be assessed, reports BBC Radio Devon.
England will play three Tests against the All Blacks this summer, starting in Auckland on 7 June.
Truro-born Nowell made his debut for Chiefs in 2011 and has gone on to appear 17 times in the Premiership for Rob Baxter's side.
