The Miami Dolphins have fired general manager Jeff Ireland.

The club made the announcement Tuesday evening, calling it a mutual agreement to part ways.

"I want to personally thank Jeff for his hard work and dedication in building the team over the past six years," said Dolphins owner Stephen Ross in a statement issued shortly after the news broke. "After a series of discussions, we both felt that it was in our mutual best interest to part ways. Jeff was a loyal and dedicated member of the Dolphins and we wish him and his family nothing but the best."

The Dolphins finished 8-8, good enough for second-place tie with the Jets in the AFC East, but fell short of a playoff berth for the fifth consecutive season. The season was also marred by internal strife originating from the investigation regarding the treatment of Jonathan Martin at the hands of fellow offensive lineman Richie Incognito and subsequent review of team policies and practices regarding player conflict.

Ireland was elevated to the GM position in January of 2008, given full power over football operations and personnel once Bill Parcells agreed to step aside in September of 2010, then was rewarded with a multi-year contract extension the following January.

Under Ireland, the Dolphins went a combined 46-50 with a wild card loss to the Baltimore Ravens following the 2008 season.

"I've spent the last six years with the best organization in football," said Ireland. "Steve and I came to an agreement that the best thing moving forward for all parties would be to part ways. I'd like to thank Steve for all his support and kindness. I've had the opportunity to work with some of the most amazing people during this time and I'd like to thank them all from the bottom of my heart."
