Raiders fire coach Dennis Allen

— -- The Oakland Raiders have fired coach Dennis Allen, a league source confirmed to ESPN NFL Insider Adam Schefter.

Allen was 8-28 as Oakland's coach. He was fired after the Raiders, who retooled their roster this offseason, started 0-4.

FoxSports.com reported the news earlier Monday night.

Oakland has lost an NFL-high 10 straight games dating back to last November and is 0-4 for the first time since 2006 when it finished with the worst record in the NFL. The final straw for Allen was an embarrassing 38-14 loss to Miami on Sunday in London. The Raiders are on their bye week.

The failure to be competitive was what doomed Allen. Oakland owner Mark Davis, who took control of the franchise when his legendary father, Al, died in November, 2011, was on the record saying he was tired of the team losing in lopsided fashion. That didn't change this season. The Raiders lost by 20 or more points in nine of Allen's 36 games as coach.

The Raiders were 8-8 in the two seasons before Allen became coach. Firing Allen is a major pockmark for Oakland general manager Reggie McKenzie. Allen was his first hire after being picked to succeed Al Davis as the football-decision maker in Oakland in January 2012.

Allen, 42, was Denver's defensive coordinator before being hired in Oakland. Now, he is another in a long line of former Oakland coaches. Al Davis was famous for hiring and firing coaches. Allen was the Raiders' seventh coach since they traded Jon Gruden to Tampa Bay after the 2001 season. It's the most in the NFL in that span.
