Arizona Cardinals defensive end Darnell Dockett has been fined a "six-figures" amount for allegedly spitting at teammate Kerry Rhodes and disobeying the team's plan to let the Jets score, a source told ESPN.

The Associated Press and Arizona Republic have reported the fine came from the Cardinals, not the NFL, citing unnamed sources.

Sources told ESPN that Dockett is appealing the fine.

"Thank God for the @nflpa that's all I got to say... 'I ain't got no worries'," Dockett tweeted on Friday.

Dockett allegedly spit at Rhodes while the two argued about the team's decision to let the Jets score near the end of a 7-6 loss to New York last Sunday. Rhodes denied that Dockett spit and Dockett apologized to Rhodes.

The issue became moot when the Jets' Shonn Greene purposely downed the ball at the Arizona 1 and ran out the clock.

Defensive coordinator Ray Horton told reporters Friday he was the one who suggested to coach Ken Whisenhunt that the Jets be allowed to score. Whisenhunt has declined to discuss the situation, calling it an internal matter.

Dockett said earlier this week he had apologized to Rhodes and the two had agreed to move on. But Dockett emphatically said he had never quit in a game and never would.

"It's something that I don't believe in, something that I didn't understand," Dockett said then. "It was frustrating at the time. At the end of the day, I am never, never going to lay down and quit. I've been playing football for over 20 years. I've given this organization, I've given Florida State, I've given my high school everything I've got. I love the game. I play with passion and I'll never quit."
