The Detroit Lions have fired general manager Martin Mayhew and president Tom Lewand.
The Lions have endured a horror start to the season and have a 1-7 record following their 45-10 drubbing by the Kansas City Chiefs at Wembley last Sunday.
Offensive coordinator Joe Lombardi was fired prior to the trip to London and replaced by Jim Bob Cooter but that move failed to pay any immediate dividends against the Chiefs.
Now the team's owners, the Ford family, have decided more drastic changes are in order to turn around the fortunes of a franchise that made the playoffs in the NFC last season with an 11-5 record.
"I want to assure our fans that we intend to identify and hire the very best leadership in order to produce a consistently winning football team," Martha Ford said.
"Our fans deserve a winning football team and we will do everything possible to make it a reality. I also want to make clear that we have no intention on giving up on the season.
Lewand was in his 20th season with the Lions, and his sixth as president. Mayhew became the team's general manager early in the 2008 season when the team fired Matt Millen.
Both executives took the fall for a franchise that is struggling after having relative success in recent years.
Detroit's offence ranks 30th in the league with just 18.6 points per game and quarterback Matt Stafford is on pace for one of the worst statistical seasons of his career behind an underperforming offensive line.
