Atlanta Falcons special-teams coach Keith Armstrong interviewed for the team's head coaching vacancy on Sunday, a source told FOX Sports.

Armstrong, 51, is considered one of the NFL's top special-teams coordinators. He has held the position in Atlanta for seven seasons following stints with Miami (2001 to 2007) and Chicago (1997 to 2000). He also has NFL experience coaching defensive backs.

Armstrong landed on the NFL's head coaching radar in 2012 when interviewing for vacancies with Chicago, Philadelphia and Kansas City. Behind the play of Devin Hester, Atlanta led the NFL in punt return average last season at 13.3 yards.

The Falcons have interviewed a slew of other head-coaching candidates since firing Mike Smith at the end of the regular season. The latest to meet with team officials Monday was former Buffalo Bills head coach Doug Marrone, a source told FOX Sports. Marrone opted out of his Bills contract last week after posting a 15-17 record in two seasons with the franchise.

Atlanta's interview with Armstrong would satisfy the NFL's "Rooney Rule" that each team must interview at least one minority candidate before filling a head-coaching vacancy.
