The Dallas Cowboys hired veteran Mike Pettine as senior defensive assistant on October 12, 2026. He will support first-year defensive coordinator Christian Parker in Dallas.
The move came days after a 24-16 loss to the Tampa Bay Buccaneers.
What happened
Schottenheimer announces the move
Head coach Brian Schottenheimer announced the hire on Monday. Pettine, 60, is coming out of retirement to join the staff.
Schottenheimer said Pettine will work under Parker's leadership, and the idea dates back to January. The team looked at two candidates but waited for the right person.
The plan was in place long before this week's loss to Tampa Bay.
The Tampa Bay loss
Dallas lost 24-16 to Tampa Bay on Thursday night. The Buccaneers started undrafted quarterback Jalon Daniels with Baker Mayfield out.
Dallas gave up a season-high 419 yards in the game. The loss dropped the Cowboys to 2-3.
Owner Jerry Jones said the defense was back where it started. Schottenheimer said the hire would have happened no matter the result.
Who is Christian Parker
Parker is in his first year as an NFL defensive coordinator. He built a strong reputation as a defensive backs coach before Dallas hired him.
Pettine was his boss when Parker earned his first NFL job in Green Bay.
Why it matters
A long coaching resume
Pettine started coaching in the NFL in 2002 with the Baltimore Ravens. He became the New York Jets' defensive coordinator in 2009.
He later coached the defensive line and outside linebackers in Baltimore. He also spent time as a consultant with the Seattle Seahawks.
He held the same role with the Buffalo Bills in 2013. He then became head coach of the Cleveland Browns in 2014.
His teams missed the playoffs in both seasons. The Browns fired him after the 2015 campaign.
Pettine ran the Green Bay Packers' defense from 2018 to 2020. He then joined the Minnesota Vikings staff as a senior assistant.
He retired after the 2025 season. Schottenheimer worked with Pettine years ago on the Jets.
Schottenheimer said the staff had two names in mind from the start. The other option never worked out, so Dallas waited for Pettine.
Pettine had been enjoying retirement with his family. He had just returned from a trip to Italy.
A respected voice in the building
In Minnesota, Pettine helped Brian Flores build one of the league's tougher defenses. Schottenheimer calls him one of the most respected defensive minds in football.
The numbers behind the move
The Cowboys rank second-to-last in yards allowed per game. They give up 395.4 yards each week.
They also allow 27.2 points per game, near the bottom of the league. The defense has shown little improvement from last season.
That is why Dallas added a veteran voice now. Parker keeps his job and his play-calling duties.
Why the fit works
Pettine and Parker already know each other well. Parker worked under Pettine in Green Bay during the 2019 season.
Pettine also understands the 3-4 style of defense Dallas runs. Schottenheimer called Pettine a sounding board for the young coordinator.
The plan adds experience without changing the leader. Dallas hopes that mix brings quick results.
The Cowboys also added cornerback Joey Porter Jr. from Pittsburgh earlier this month. He missed the Tampa Bay game because of illness.
His return should strengthen the secondary.
What happens next
A quick reunion in Green Bay
Pettine starts work with the Cowboys on Tuesday. Five days later, Dallas visits the Green Bay Packers on Sunday night.
Pettine ran Green Bay's defense from 2018 to 2020. The trip is a homecoming for both Pettine and Parker.
Parker also began his NFL career under Pettine there. All eyes will be on how the defense responds.
What to watch
Watch how Dallas uses Pettine on game day against Green Bay. He will advise Parker from the sideline.
Parker remains in charge of calling plays. The NFL keeps producing wild finishes, and Dallas cannot afford another slow start.
A fast start on defense would change the mood fast. The new cornerback could help make that happen.
The bigger question
The real question is whether advice alone can fix the defensive numbers. Dallas needs better tackling, coverage and pressure.
Those problems start with the players, not the coaches. For now, the Cowboys are betting on veteran experience.
Pettine has coached in the NFL since 2002. Parker gets a mentor he already knows and trusts.
If the defense improves, this hire will look like a smart and quiet move. If it does not, the questions around Parker will only grow.
Either way, Sunday night in Green Bay is the first real test.
