Worcester director of rugby Gary Gold will leave Sixways at the end of the season to become head coach of the USA Eagles.
Gold -- who joined Worcester midway through the 2016-17 season -- will see out the remainder of his contract with the Aviva Premiership club, which runs until May.
The club revealed in a statement released Monday that the 50-year-old former South Africa assistant coach will be tasked with helping the Warriors appoint his successor.
"I would like to thank Bill [Bolsover, Worcester chairman] and the board for understanding my decision to accept the opportunity to coach at international level.
"I have thoroughly enjoyed my time at Sixways and my focus will remain on Warriors until the end of the season, where I hope to leave the club in a strong place to ensure it can be successful in the long-term."
Gold helped Worcester avoid relegation to the RFU Championship last season but the club have found the going tougher this term.
The Warriors are currently bottom of the Premiership table, having picked up only one point from their opening five matches.
"We are naturally disappointed that Gary will be leaving the club at the end of the season but we fully understand his desire to coach at an international level," Bolsover said.
"We are working with Gary to ensure we can appoint a director of rugby who is capable of building on the good work he and his coaching team have done this year, and someone who is able to take us forward as Gary has done.
"We are confident Gary will be able to oversee a successful season for the Club before he takes on his new position."
