Alex Grove looks set to join Edinburgh on a year-long loan from Worcester in a bid to impress ahead of the 2011 World Cup.
The Warriors, who were relegated after finishing bottom of the Guinness Premiership this season, have confirmed negotiations with Scottish Rugby are underway.
The 22-year-old back was given his first cap for Scotland in November and played in all three autumn internationals after helping his country's A side win the IRB Nation's Cup.
Despite the temporary transfer to the Magners League, Worcester insist that Grove is not seeking a permanent move away from Sixways.
"Worcester Warriors can confirm it is in discussion with the SRU and Scotland head coach Andy Robinson," the club stated.
"Alex's long-term future remains with Worcester Warriors.
"His attitude off the pitch and ability on it makes him an important part of our future.
"Alex has spoken to the chairman to reiterate his long-term commitment and desire to extend his contract at Sixways in the near future."
Grove, who qualifies for Scotland through his grandfather, was not featured at any point during the RBS Six Nations but has been named in Robinson's squad for next month's tour to Argentina.
