Worcester Warriors have confirmed that Alan Solomons will take over from Gary Gold as director of rugby in the new year.
Gold was initially due to depart at the end of the season to become head coach of the United States national team, but he will now begin his new role in January.
Solomons, who was appointed as Gold's assistant in October, has agreed a two-and-a-half-year deal at Sixways.
The 67-year-old brings a wealth of experience, having previously enjoyed coaching stints with the likes of Western Province, the Stormers, South Africa, Ulster and Edinburgh.
"I have enjoyed my time at Warriors since day one and it has become clear that the club has masses of potential to be successful in the long-term," Solomons said.
"I am hugely excited about being given the opportunity to lead this club and I am looking forward to continuing the hard work to ensure we can build for the future, move up the Premiership table and give the supporters the success they deserve."
"I would like to thank the club for allowing me to bring my contract to an end at this time to begin my role with the USA in January," added Gold.
"I have thoroughly enjoyed my time at Sixways. I feel the club has taken steps forward over the last year and has the foundations to ultimately be successful. I wish all the players and staff the best of luck in the future."
Worcester defeated London Irish 23-8 on Friday to move 10 points clear of their opponents at the bottom of the Premiership. They have won two and lost two of their four games in the European Challenge Cup to sit second in Pool 5, seven points behind Connacht.
