University of Oregon trustees on Thursday unanimously approved a new six-year, $27 million contract for Ducks coach Mario Cristobal.

The agreement extends Cristobal's original contract by two years through the 2025 season. His salary will increase from $2.7 million to $4.3 million in January, and the coach will earn an average of $4.55 million during the term.

Cristobal could also trigger a $5 million option for the 2026 season if the Ducks either: win nine regular-season games in 2021, '22 or '23; win 10 games in 2024; or win the Pac-12 North in any of those four seasons.

Athletic director Rob Mullens, in a call Thursday morning with the trustees, said the new contract would put Cristobal among the top four Pac-12 coaches in salary and in the top 25 nationally.

Mullens and university president Michael Schill both praised Cristobal's on-field accomplishments, recruiting success and culture building in the call with trustees.

Oregon on Wednesday signed a recruiting class that is ranked No. 6 nationally by ESPN.

Cristobal's salary had ranked 11th out of 12 among Pac-12 coaches. The new agreement increases his performance incentives, and the salary pool for his assistants and staff also is expected to go up. His buyout will rise from $8 million to $9 million until January 2022, before dropping to $6.5 million and then to $4 million the following year.

Oregon promoted Cristobal to head coach after Willie Taggart left for the Florida State job in December 2017.

Cristobal, 50, is 24-9 with the Ducks, who aim for their second consecutive Pac-12 championship Friday against No. 13 USC. The former Miami offensive lineman went 27-47 in six years at Florida International from 2007 to 2012.

Cristobal's name had been mentioned as a potential candidate for Auburn's coaching vacancy.
