The Cleveland Browns relieved head coach Mike Pettine and general manager Ray Farmer of their duties on Sunday.
The Browns will begin the 2016 season with their sixth GM and seventh head coach since firing Butch Davis after the 2004 campaign.
Owner Jimmy Haslam met with both Farmer and Pettine after Sunday's 28-12 home loss to the Pittsburgh Steelers, which dropped the Browns to 3-13.
"We greatly appreciate Ray and Mike's dedication and hard work while with the Cleveland Browns," Haslam said in a statement.
"We've made this decision because we don't believe our football team is positioned well for the future. We are all disappointed with where we are and I take full responsibility.
"We will approach the search for our next football coach and executives to lead our football operations with a clear vision regarding what we need to do to build a successful organisation.
"We will be methodical in looking for strong, smart leaders with high character who are relentlessly driven to improve our football team, willing to look at every resource possible to improve, and who embrace collaboration to ultimately make the best decisions for the Cleveland Browns.
"We are fully committed to bringing our fans the winning organisation they so clearly deserve."
The Browns used three different starting quarterbacks this season, with Austin Davis getting the nod in the season finale.
Pettine and Farmer were hired in 2014 and the Browns started that season 7-4, but they lost five straight to close the campaign before this year's disappointment.
Johnny Manziel led the team to two of the team's three wins this year even though journeyman veteran Josh McCown was the week one starter.
The Browns entered the 2015 season with high expectations after finding early success last year.
