Chris Mortensen cites the development of Browns QB Baker Mayfield as a potential reason for the firing of Todd Haley. (0:46)

The Cleveland Browns fired coach Hue Jackson and offensive coordinator Todd Haley on Monday after a three-game losing streak derailed a promising start to the season.

The Browns also announced that defensive coordinator Gregg Williams, who is in his second season with Cleveland, will be the interim coach. Running backs coach and associate head coach Freddie Kitchens will serve as offensive coordinator. Although there was speculation that Williams' son Blake Williams could be the Browns defensive coordinator, the team said that Gregg Williams will serve in both roles.

The Browns are 2-5-1 this season, doubling the win total from Jackson's first two seasons with the team. Cleveland was 1-15 in his first season and 0-16 last season. The Browns hired John Dorsey as general manager late last season, and Dorsey kept Jackson on as coach despite the team's winless season.

There were rumblings that the relationship between Jackson and Haley had deteriorated to the point that a move might have to be made. Haley was in his first season with the Browns after serving as the Steelers' offensive coordinator from 2012 to '17.

The changes also were made with the development of quarterback Baker Mayfield, the team's No. 1 overall draft pick, in mind, sources told ESPN's Chris Mortensen.

"We greatly appreciate Hue's commitment to the Cleveland Browns organization over the last two and a half years," Browns owners Dee and Jimmy Haslam said in a statement. "We understand how critical this time period is in the development of our football team, individually and collectively, and believed it was in the organization's best interest to make the move at this time, in order to maximize our opportunities the rest of this season. We certainly only wish Hue, Michelle, and his family the best moving forward."

After the news surfaced of the Browns' changes, Mayfield's college coach, Oklahoma's Lincoln Riley, was asked whether he had any interest in coaching in the NFL.

"I knew that was coming," Riley said during his weekly news conference. "No, not right now. You sit here and answer these questions, and I always want to be truthful. The truth is for me is I love Oklahoma. I love coaching here. I love college football. I certainly don't have that itch right now. Don't know that I ever will.

"But I'm never going to be a guy that stands up here and say no way, no how, with any of these things never happening. I don't know that. But I know right now I could care less about the NFL."

The Browns lost to the Steelers 33-18 on Sunday after playing to a tie with Pittsburgh in the season opener. The previous five Browns head coaches -- Romeo Crennel, Eric Mangini, Pat Shurmur, Rob Chudzinski and Mike Pettine -- were all fired after the second Steelers game of that season.

play 1:40 Jackson fired by Browns Adam Schefter reacts to the Browns' decision to fire head coach Hue Jackson after he compiled a 3-36-1 record.

Jackson, 53, had one season of head-coaching experience before coming to Cleveland, guiding the Raiders to an 8-8 record in 2011.

Since 2016, the Browns are last in the NFL in win percentage, offensive efficiency, points per game and total quarterback rating. Jackson's career .205 win percentage is second worst in NFL history among all coaches with at least 40 games. According to the Elias Sports Bureau, Jackson's 3-36-1 record with the Browns is the worst head-coaching record for one team in NFL history (minimum 40 games).

Seven quarterbacks started for Jackson's Browns, and only Tyrod Taylor didn't have a losing record:

The Browns also went 0-20 on the road during Jackson's tenure, the worst road record by any coach with a team in the Super Bowl era (since 1966).

The Browns host the 7-1 Chiefs on Sunday.

Williams has extensive experience as a defensive coordinator in the NFL and was the Bills' head coach from 2001 to 2003. He is perhaps best known for being suspended by the league for a year in 2012 after admitting to his role in the Saints' bounty scandal.

Jackson's firing comes one day after the Cleveland Cavaliers fired coach Tyronn Lue, who led the team to an NBA title in 2016 but was struggling in his first season without star LeBron James.
