New Orleans made the move after Garrett Hartley missed a field goal try of 29 yards in overtime last Sunday that would have given the defending Super Bowl champion Saints a victory over Atlanta. The Falcons went on to defeat New Orleans 27-24.
Hartley is in his third season with New Orleans and kicked the winning 40-yard field goal in overtime against Minnesota last season in the NFC championship contest.
Carney has been in the NFL for 22 seasons and has kicked for nine teams. This will be his third stint with the Saints. He made 13-of-17 field goal attempts and 50-of-52 extra points in 2009 before being released by the Saints in December. Hartley replaced Carney for the final five games of the regular season and the playoffs.
Carney was retained as a kicking consultant after being removed from the roster last year.
He kicked for the New York Giants in 2008, compiling a career-best 143 points in 15 games.
In order to keep both kickers on the roster, the Saints waived wide receiver Adrian Arrington. There was no immediate indication as to who would kick for New Orleans this Sunday against Carolina.
