Speculation about potential suitors for Peyton Manning continued to swirl Sunday, with ESPN reporting that Arizona will join the Dolphins, Jets and Redskins as teams interested in the star quarterback if the Colts set him free.

Manning sits atop the Dolphins’ quarterback wish list this offseason, and they will aggressively pursue him if he’s a free agent and if he’s cleared medically, two people with direct knowledge of Miami’s plans said in the past week.

If Manning-to-Miami does not materialize, the Dolphins will turn to other options, including Packers impending free agent Matt Flynn or an attempt to trade up to draft Baylor’s Robert Griffin III.

The Colts must decide by March 8 whether to pay a $28 million roster bonus to Manning, who is still rehabilitating from neck surgery.

Colts owner Jim Irsay told NFL Network last month that if Manning can get healthy, he will be back with the team. But the surgically repaired nerves in his neck continue to regenerate, and his health remains a question.

Manning, 35, reportedly would not be willing to push back the deadline to give the Colts more time to make a decision. With Indianapolis positioned to draft Stanford’s Andrew Luck, some in the league believe the Colts might set Manning free. Irsay said Saturday the Colts will draft a quarterback with the No. 1 pick.

Because of the size of his contract, it’s highly unlikely Manning would be traded. ESPN’s Chris Mortensen said Sunday there’s “nothing certain on Manning’s future.’’

• As Mortensen first reported, Dolphins coach Joe Philbin met Sunday with former NFL offensive lineman Andy Heck about the Dolphins’ offensive line coaching job. Heck served in that role for the Jacksonville Jaguars since 2004 before Mike Mularkey recently took over as the team’s coach.

• Add Bengals assistant Kevin Coyle to the list of names reported as a possibility for the Dolphins’ defensive coordinator job. Coyle has been Cincinnati’s defensive backs coach for 10 years. Philbin has autonomy in assembling his staff.

• Philbin will not attend Senior Bowl practices, which begin Monday in Mobile. Dolphins general manager Jeff Ireland will discuss the state of the team with reporters on Tuesday.
