MIAMI — New Dolphins coach Dan Campbell believes his underachieving team needs to show more aggressiveness that stops just short of dirty play, and he looks forward to breaking up a few fights in practice.
Joe Philbin he's not — which was the motive for Miami's coaching change Monday.
Owner Stephen Ross fired Philbin four games into his fourth season, and one day after a flop on an international stage helped seal his fate.
Tight ends coach Campbell was promoted to interim coach. The former NFL tight end's only coaching experience is with the Dolphins, who hired him as an intern in 2010.
"I'm not here just to finish the season up," said Campbell, 39, a Bill Parcells disciple. "That's not my plan. We're coming here to win games. … We have time to turn everything around. But we can't wait."
The Dolphins lost their third game in a row Sunday with a fourth consecutive lackluster performance, a 27-14 loss to the Jets in London.
Philbin reportedly lost control of his team; Ryan Tannehill had a testy exchange with linebacker Chris McCain during Saturday's walk-through in London after McCain picked off a pass. The starting quarterback reportedly told the scout team defenders "enjoy your practice squad paychecks."
An altercation ensued, and after coaches got things under control, the defenders aggressively went after more of Tannehill's passes, then stopped practicing when coaches discouraged them from doing so.
Tannehill, who got a five-year, $95 million extension in the offseason, was 19-of-44 for 198 yards Sunday. Another big-money player, defensive tackle Ndamukong Suh, has 10 tackles and no sacks through four games. Suh signed a six-year, $114.4 million contract in the offseason after leaving the Lions; nearly $60 million of that money is guaranteed.
Campbell said he wasn't ready to make any decisions regarding possible changes in the rest of the staff.
Philbin, hired in 2012, went 24-28. He failed to reach the playoffs or finish above .500 in any season. His tenure also included the 2013 bullying scandal.
"It is my hope that the 2015 Miami Dolphins achieve great success both on and off the field," he said in a statement.
Seahawks hang on
SEATTLE — Seahawks safety Kam Chancellor saved the game and perhaps the season Monday night for the two-time defending NFC champions.
Chancellor, who ended his contract holdout in time to return to action last week, forced Lions receiver Calvin Johnson to fumble just inches before he would have scored a go-ahead touchdown as Seattle beat Detroit 13-10.
The Seahawks evened their record at 2-2 and handed the Lions their fourth straight loss to open the season.
Luck back, sort of: After missing his first NFL game Sunday because of an injured right shoulder, Colts quarterback Andrew Luck returned to a light practice and lobbed two short screen passes to running backs during the portion open to reporters. Luck was listed as a limited participant with his status day to day heading into Thursday's game against the Texans. Also, the Colts cut former Bucs quarterback Josh Johnson, who was signed last week with Luck out.
Brees better: Saints quarterback Drew Brees stopped short of saying he was 100 percent a day after leading New Orleans to an overtime victory over Dallas. He settled for saying his arm was good enough to do the job, and his numbers did bear that out, even if some throws floated off target. Completing mostly short passes, Brees finished 33 of 41 for 359 yards and two touchdowns including the winning 80-yarder to running back C.J. Spiller.
Bears: Center Will Montgomery broke his left fibula Sunday against the Raiders.
Cowboys: Running back Lance Dunbar has a torn ACL in his left knee and needs surgery, coach Jason Garrett said.
Redskins: Tight end Jordan reed was in the league's concussion protocol after Sunday's win over the Eagles, and also had a sprained MCL and ankle, coach Jay Gruden said.
Texans: The team is sticking with Ryan Mallett at quarterback despite his recent struggles. Mallett threw an interception and didn't lead the Texans to any points before was replaced by Brian Hoyer late in a 48-21 loss to the Falcons on Sunday.
