Jon Gruden filed a lawsuit against the NFL and Commissioner Roger Goodell in Nevada district court on Thursday, alleging they leaked private emails to The New York Times and The Wall Street Journal to force him out of a head coaching job with the Las Vegas Raiders.

Gruden is seeking damages on seven different claims as well as punitive damages and lawyer fees.

"Jon Gruden has filed suit against the National Football League and Commissioner Goodell in the Eighth Judicial District Court in Clark County, Nevada. The complaint alleges that the defendants selectively leaked Gruden’s private correspondence to The Wall Street Journal and New York Times in order to harm Gruden’s reputation and force him out of his job," Gruden’s attorney, Adam Hosmer-Henner, said in a statement to Fox News Friday.

"There is no explanation or justification for why Gruden’s emails were the only ones made public out of the 650,000 emails collected in the NFL’s investigation of the Washington Football Team or for why the emails were held for months before being released in the middle of the Raiders’ season."

In a 21-page complaint obtained by Fox News, the NFL and Goodell are alleged to have "sought to destroy the career and reputation" of Gruden through "a malicious and orchestrated campaign."

The complaint drew a contrast to how Gruden’s emails were handled to how the league’s investigation into the Washington Football Team ended. Snyder was fined $10 million, but there was no written report revealed in the probe.

"In contrast to the formalities of the Washington Football Team investigation, defendants’ treatment of Gruden was a Soviet-style character assassination. There was no warning and no process. Defendants held the emails for months until they were leaked to the national media in the middle of the Raiders’ season in order to cause maximum damage to Gruden," the complaint states.

The NFL responded to the lawsuit Friday.

"The allegations are entirely meritless, and the NFL will vigorously defend against these claims," NFL spokesman Brian McCarthy said.

Gruden and the Raiders parted ways last month after a litany of emails were leaked and published in The Wall Street Journal and The New York Times. Gruden exchanged racist and misogynistic messages with then-Washington team president Bruce Allen while working for ESPN. 

The leaked messages created a firestorm and led to Gruden losing his job with the Raiders.

It has remained unclear who leaked the emails to the outlets. The NFL and Washington team owner Daniel Snyder have both been accused of leaking the messages, and both have denied doing so.

Gruden apologized for his comments about NFLPA executive director DeMaurice Smith and other remarks he made in the emails with Allen. The complaint also made note of support Gruden received from former NFL stars Randall Cunningham and Tim Brown, who are both Black.
