Jon Gruden says he didn't see the firing of Reggie McKenzie coming.

"He was a very good friend, and he's always gonna be a Raider," Gruden said. "We're going to have to rebuild this team without him. ... He's left some big shoes to fill."

Gruden claims he never saw "any disconnect" and all he knows is "we won a game, and I went home last night. Obviously there was a meeting last night, and obviously changes have been made. I respect everything this organization is about. I can't exactly answer why the changes were made last night, but changes were made. ...

"We all work for the same man."

Gruden put the decision on Mark Davis, who hired him to run football operations.

"Like I said, I was just done coaching a game yesterday," Gruden said. "Mark will accumulate a list of names and candidates. Right now I don't have any idea. ... I'm not revealing any candidates because I don't know any."
