Dolphins preparing to fire coach Joe Philbin after 1-3 start

— -- The Miami Dolphins were preparing to fire coach Joe Philbin as of Sunday night, league sources tell ESPN.

Dolphins owner Stephen Ross could always change his mind, but the organization was preparing to make a move as soon as Monday, the sources said.

If Ross follows through and fires Philbin, Dolphins tight ends coach Dan Campbell would be the leading candidate to become the interim head coach and replace Philbin.

Philbin met with Ross on Sunday in London after a 27-14 loss to the New York Jets dropped Miami to 1-3 this season, and said afterward that he was confident in his job security. 

Philbin is 24-28 in Miami since taking over in 2012.
