MIAMI — Jeff Ireland is out after six seasons as general manager of the Dolphins, who have missed the playoffs the past five years.
In a brief announcement Tuesday, Ireland and owner Stephen Ross said they mutually agreed to part ways. Ireland had been unpopular with fans for several years, and a late-season collapse by the team last month left his job in jeopardy.
The Dolphins, who finished 8-8, said they would conduct an immediate search for a replacement to lead football operations.
Still to be determined is Ireland's role in a locker-room bullying scandal that drew national scrutiny. The NFL has yet to release a report on its investigation into the case.
Ireland's departure follows Monday's firing of offensive coordinator Mike Sherman. Coach Joe Philbin returns for a third season.
Ireland, in a statement, said: "I've spent the last six years with the best organization in football. Steve and I came to an agreement that the best thing moving forward for all parties would be to part ways."
Giants: Former Florida State receiver Preston Parker was one of five players to sign as free agents.
