Durde played for the Scottish Claymores from 2003 until 2004 when team operations were permanently suspended by NFL Europe due to low attendance numbers and an increased league focus on the German market.[2]
Following the conclusion of the NFL Europe season Durde was allocated to the Carolina Panthers on June 15, 2005, as part of the NFL International Development Practice Squad program.[3]
On October 19, 2005, Durde was released from the Panthers practice squad after testing positive for nandrolone on August 1 during a routine preseason drug test.[4]
After his departure from the Carolina Panthers, he returned to the Sea Devils for the 2006 NFL Europe season.
He was a member of Hamburg's 2007 NFL Europa World Bowl XV championship winning team.[5] 2007 would be his last season with the Sea Devils due to the league ceasing operations following the conclusion of the season.[6][7]
Durde served as the head of football development at NFLUK from 2015 to 2018.
Concerned about the lack of a defined route into the league for players who did not go to high school or college in the United States, Durde worked alongside another British ex-NFL player - Osi Umenyiora - to create a training program and set-up meetings and try-outs with NFL teams. The initial iteration of this training camp in 2016, featured a small number of specifically selected football players who were currently playing amateur football in Europe. The training program came with the support of the NFL and was the subject of a 12-episode documentary series produced by NFL Films titled "NFL Undiscovered".[11] Following the success of the program the NFL created the International Player Pathway Program in 2017.[12][13]
In 2016, Durde joined the Atlanta Falcons under the Bill Walsh NFL diversity coaching fellowship.[14]
On April 11, 2018, Durde was hired by the Atlanta Falcons as their new defensive quality control coach under head coach Dan Quinn.[15] This hiring made him the first ever British full-time coach in NFL history and the first full time coach from outside the United States.[1][10]
In 2020, he was promoted to outside linebackers coach.[16]
On February 13, 2024, Durde was hired by the Seattle Seahawks as their defensive coordinator under head coach Mike Macdonald.[18] Durde again made league history with this hiring, becoming the first British-born defensive coordinator in league history.[1]
