Darrell Bevell and Kris Richard reportedly have been fired as Seattle Seahawks offensive and defensive coordinator Wednesday in a staff shake-up.

Curtis Crabtree of Sports Radio KJR in Seattle first reported word of Bevell's exit, with Dave Mahler of 950 KJR breaking news of Richard's exit along with quarterbacks coach Carl Smith.

Gregg Bell of the Seattle Times confirmed Richard's exit.

NFL Network's Ian Rapoport added that Seahawks head coach Pete Carroll believes Richard could benefit from "experiencing something new."

Per Rapoport, Atlanta Falcons offensive coordinator Steve Sarkisian is a top target to replace Bevell, but Falcons head coach Dan Quinn said there was "zero chance of that."

Bevell had been the Seahawks' offensive coordinator since 2011, helping to guide them to two Super Bowl appearances and one title.

Prior to joining the Seahawks in 2011, Bevell had a five-year stint as the Minnesota Vikings' offensive coordinator, as well as a run as the Green Bay Packers' quarterbacks coach.

Bevell replaced Jeremy Bates as Seattle's offensive coordinator prior to Pete Carroll's second season as the Seahawks' head coach.

In his seven seasons as Seahawks offensive coordinator, Bevell guided them into the top 10 in points scored four times.

The Seahawks were 11th in that category in 2017, and they ranked 15th in total offense.

Much of Seattle's offensive success this season was due to quarterback Russell Wilson, who threw for 3,983 yards and an NFL-leading 34 touchdowns. Additionally, he led the Seahawks in rushing with 586 yards and three touchdowns.

The Seahawks had just four rushing touchdowns as a team, and Mike Davis was their leading rusher among running backs with just 240 yards.

Bevell's Seahawks tenure may best be remembered for his role in the play call that cost Seattle Super Bowl XLIX against the New England Patriots in February 2015.

Rather than having his team hand the ball to running back Marshawn Lynch, Bevell called a pass, and Wilson was intercepted on 2nd-and-goal from the Patriots' 1-yard line with just seconds remaining by Patriots cornerback Malcolm Butler.

Seattle lost 28-24 despite leading by 10 entering the fourth quarter.

Richard was the Seahawks' defensive coordinator from 2015 through 2017 after spending five seasons as a secondary coach in Seattle.

He previously enjoyed a five-year NFL playing career as a cornerback, playing three of those seasons for the Seahawks. Richard played under Carroll collegiately at USC.

Seattle ranked first in both total defense and points allowed in 2013 and 2014. The Seahawks were second in total defense and first in points allowed during Richard's first year as defensive coordinator, and fifth and third in those two categories respectively in 2016.

With injuries to key defensive players such as cornerback Richard Sherman and safety Kam Chancellor, the Seahawks fell to 11th in total defense and 13th in points allowed this season.

In 2017, the Seahawks finished 9-7 and missed the playoffs for the first time since the 2011 campaign.
