Marrone opted out his contract with the Bills last week after only after two seasons because of concerns about Buffalo's new ownership. He can negotiate a new contract with other teams and still collect his $4 million salary that the Bills owe him for the 2015 season.
The New York Jets are also reportedly interested in hiring Marrone, who had a 15-17 record in his two years in Buffalo.
Atlanta has requested to interview Arizona Cardinals defensive coordinator Todd Bowles and Detroit Lions defensive coordinator Teryl Austin. The team also plans to interview former Jets head coach Rex Ryan.
Marrone is the only offensive coach on Atlanta's reported list of coaching candidates.
The Falcons fired Mike Smith last week after seven seasons with the team.
