Del Rio extends Raiders contract

Updated: 

Oakland Raiders head coach Jack Del Rio has been rewarded with a new four-year contract.

The Raiders made the announcement on Friday, after Del Rio led Oakland to a 12-4 season and their first NFL playoff appearance since the 2002 campaign.

"The Raiders have torn up Jack Del Rio's original contract and rewarded him with a new four-year deal," owner Mark Davis said in a statement.

"We are excited to continue building on the strong foundation that has been established and this is a significant step in achieving that goal."

Del Rio went 7-9 in his first season in Oakland but enjoyed success with the emergence of third-year players, quarterback Derek Carr and pass rusher Khalil Mack, who was named the 2016 Defensive Player of the Year. 

Before Oakland, Del Rio spent nine seasons with the Jacksonville Jaguars, going 12-4 in 2005.

The Jags went 8-8 the next season, followed by an 11-5 campaign.

Del Rio will have a new offensive co-ordinator in Todd Downing but will retain defensive co-ordinator Ken Norton Jr.
