Worcester Warriors have announced that Dean Ryan has left his role as director of rugby with immediate effect.
Ryan, who has previously coached at Bristol Rugby and Gloucester, took on the director role in April 2013.
The club have confirmed that head coach Carl Hogg and high-performance director Nick Johnston will now report to chief executive Jim O'Toole.
"We are very sorry to see Dean move on from Sixways," O'Toole told the club's official website. "He has been instrumental in developing and putting in place our long-term plan and we have been delighted with our progress and the momentum we have built up over the last three years.
"Dean has also helped to build a team around him who are ready to step-up to the next level and build on that progress. For the first time in Warriors' history we have an active succession plan which has already kicked in. We are an ambitious club with sights on the top six places in the Premiership and the Champions Cup."
Worcester finished 10th in the 2015-16 season.
