Report: Dennis Allen informed by Oakland Raiders that he's been fired

The Oakland Raiders have informed Dennis Allen that he has been fired, Fox's Jay Glazer reported.

Allen's Raiders dropped to 0-4 — their 10th straight loss dating back to last season — after Sunday's 38-14 defeat to the Miami Dolphins in London.

And it apparently happened Monday over the phone, per NFL Network's Ian Rapoport, despite Allen and the team having to spend 12 hours on a plane together coming back from overseas.

It has been widely speculated that either assistant head coach/offensive line coach Tony Sparano or offensive coordinator Greg Olson would replace Allen on an interim basis.

This was the call of owner Mark Davis. General manager Reggie McKenzie might also be on the hot seat given the status of the Raiders' shaky roster.

There was a report by the Associated Press that Allen would be fired, but it was retracted. The Raiders returned from London on Monday but no announcement was made.

Allen's contract ran through the 2015 season.

Allen was on borrowed time after an 8-28 record in his two-plus seasons as the Raiders' head coach.

The Raiders are on bye in Week 5. They face the San Diego Chargers in Week 6.
