Chris Adams is to stay with champions Sussex after a dramatic change of heart over his decision to join Yorkshire.
Adams has turned Sussex into a force in county cricket
Adams had agreed a four-year deal to become captain and director of pro cricket at Headingley.
But the 36-year-old informed Yorkshire officials on Tuesday that he felt the combined role was too much at this stage of his career.
"We are shell-shocked by his decision to remain with Sussex," said Yorkshire chief executive Stewart Regan.
"We offered him the chance to carry on with his playing career whilst providing the opportunity he desired to move into a managerial role.
"It is a big job, that is true, but Chris and our board felt that it was a challenge he was up to and it is very disappointing that he will now not be coming to Headingley Carnegie."
Adams made his decision only hours after meeting the rest of the players for the first time and outlining plans for the future.
We are all extremely pleased he will remain a Sussex man

"I appreciate his honesty in advising us of his decision before moving to the club," Regan added.
Yorkshire now face serious problems, having already relieved David Byas of first-team responsibilities to make way for Adams.
He is still considering an alternative role as director of cricket development.
But their disappointment was mirrored by a mood of elation at Hove.
"When Chris informed us that he would not be taking up Yorkshire's offer, we were thrilled at the news," said Sussex chief executive Gus Mackay.
"Chris has been so much a part of the Sussex success story that although we wished him well with his new venture we knew he would be missed.
"We are all extremely pleased that he will remain a Sussex man."
