Philbin met with team owner Stephen Ross and general manager Jeff Ireland in New York City, where Ross has an office. Todd Bowles, the Dolphins' interim coach for their final three games this season, also interviewed Wednesday for a second time. Denver Broncos offensive coordinator Mike McCoy had his second interview on Thursday.
McCoy was scheduled to interview Wednesday with the Oakland Raiders, but he went to New York to meet with Ross instead, league sources told ESPN NFL Insider Adam Schefter.
The three coaches are finalists for the job after top choice Jeff Fisher turned down the Dolphins on Friday to become head coach of the St. Louis Rams.
Philbin completed his first interview in South Florida on Jan. 7, and he decided to remain in consideration despite his son's recent drowning in a Wisconsin river. After spending a week away, Philbin rejoined the Packers on Sunday for the divisional playoff loss to the New York Giants.
Philbin has also decided to interview for the Tampa Bay Buccaneers head coaching position this week, league and team sources told ESPN senior NFL analyst Chris Mortensen.
"He's a special, special human being," Packers coach Mike McCarthy said Wednesday. "What Joe has gone through, and what his family has gone through, obviously tough is not the proper word. ... His ability to come back meant a lot to all of us. It was not expected, it was not asked of him. But Joe's a class act. ...
"I think he would make an excellent head coach," McCarthy said. "I've said that before."
Philbin has been with Green Bay since 2003 and has been offensive coordinator since 2007, although McCarthy calls plays.
McCoy completed his first interview with Miami on Monday. He won praise for adapting the offense at midseason when Tim Tebow became the starting quarterback, and the Broncos made an improbable run to the second round of the playoffs before losing Saturday at New England.
The Raiders interviewed Bowles last Friday.
Bowles was assistant head coach and secondary coach before taking over the Dolphins when they fired Tony Sparano last month with three games to go in his fourth season as coach. Bowles became the sixth coach since 2004 for the Dolphins, who finished 6-10 and haven't won a playoff game since 2000.
After being rejected by Fisher, Ross said the team planned to interview several more candidates. But they may want to move more quickly now that the Indianapolis Colts are looking for a coach. The Colts fired Jim Caldwell on Tuesday.
