Kieran McGeeney is back in the hunt for a new Kildare selector after Niall Carew stepped down with immediate effect.
Carew has been ever-present with McGeeney (right) since the former Armagh captain took over in 2007.
His departure has come as a surprise, given that Kildare County Board ratified McGeeney as U-21 manager with Carew as a selector only two weeks ago in addition to their senior duties.
A statement confirmed his departure, outlining how Carew felt "the time is now right to step down and give Kieran the opportunity to freshen up his management team for 2013.
"He has no doubt that Kildare has the best manager in the business and it is only a matter of time before they win some much-desired and deserved silverware."
After much speculation, Mayo last night confirmed the appointment of former Kerry coach Donie Buckley to James Horan's set-up.
Buckley stepped down from Jack O'Connor's Kerry management team earlier this year and had initially been touted as a possible candidate in Eamonn Fitzmaurice's new regime.
However, Kerry last week opted to bring on board this year's Mayo trainer Cian O'Neill, who is based in Limerick.
Buckley will now go in the opposite direction and succeed O'Neill: "We are delighted to have acquired the services of someone as talented as Donie Buckley and look forward to working with him," said a Mayo statement.
Meanwhile, Dr Niall Moyna has emerged as the new favourite to be the next Roscommon manager.
Roscommon are expected to confirm an appointment this week, with sources indicating that Moyna, who was involved with Dublin for the last four years in an advisory capacity, is in the frame.
In his current capacity as manager of DCU, where he is head of the university's department of health and human performance, Moyna has been involved with several Roscommon players at third level in recent years.
One of the early front-runners, former Offaly manager Gerry Fahy, withdrew his interest yesterday.
