The Miami Dolphins will keep Philbin and general manager Jeff Ireland in place, according to a source with knowledge of the team’s plans.
Philbin was let go as a free agent following the team failed to make the playoffs the previous two seasons.
Philbins exit is expected to be finalized by Thursday, the source said.
Phils departure leaves a big hole in the front office, which has had no head coach since Mike Sherman resigned as head coach in January.
Dolphins owner Stephen Ross, who bought the team in 2000, is the front-office executive.
Ross has hired Philbin’s son, Joe, as his new general manager.
Dolphins president Mike Tannenbaum and Ross have spoken about their plans to hire an offensive coordinator in the next month.
The Dolphins’ offensive coordinator, Doug Marrone, also is a former NFL offensive coordinator.
A source said Ross plans to use his executive powers to hire a head coach this week.
