The Saints have put place kicker Garrett Hartley on injured reserve, ending his season and leaving 41-year-old veteran John Kasay as their primary place kicker for this season.
The transactions were posted by the NFL on its website on Tuesday.
Hartley, 25, has been sidelined since hurting his right hip in the third exhibition game of the preseason.
Kasay, now in his 21st season, has made all six of his field goal attempts in the Saints’ first three games, including one from as long as 53 yards and four from beyond 30 yards.
The Saints also have released defensive tackle Mitch King, a second-year pro who has played a reserve role in New Orleans’ first three games and has been credited with three tackles.
