No news on an actual firing yet per any national sources, but, too many sources have said he will be fired.
Per PFT ( http://www.profootballtalk.com/category/rumor-mill/ )
"The last straw had nothing to do with wins or losses. Gay predicts that owner Al Davis will seize upon Kiffin’s blame-shifting from last Wednesday regarding the team’s defensive performance in Week One as proof of insubordination, which then will justify firing Kiffin and not buying out the balance of his contract."
My guess it will be either this week or next week. Kinda tough to fire a coach after a win. But if he uses insubordination as the reason he can do it whenever. Also, if it's insubordination he does not have to pay the contract, although it is kinda tough to prove insubordination (see John Butler versus Ralph Wilson).
Hope it is not this week , don't need to give the Raiders any motivation.
