The New Orleans Saints put kicker Garrett Hartley on injured reserve Tuesday and made several other roster moves to help out with a growing injury list going into Sunday’s game against the Jack-sonville Jaguars.

Saints General Manager Mickey Loomis confirmed Tuesday night that Hartley, who has been sidelined since injuring his hip while kicking an extra point in an Aug. 28 exhibition game at Oakland, will miss the rest of the season after being put on injured reserve.

When Hartley was injured, the Saints may have thought the four-year veteran would return sometime in October. While Loomis didn’t offer any reason for the move, it’s possible they felt they couldn’t keep two kickers on the 53-man roster after a series of injuries in Sunday’s 40-33 win over the Houston Texans.

With wide receiver Marques Colston (shoulder), middle linebacker Jonathan Vilma (knee) and cornerback Tracy Porter (calf) already sidelined for the Texans’ game, the Saints lost center Olin Kreutz (undisclosed) and right tackle Zach Strief (knee) during the contest.

Also hurt Sunday were strongside linebackers Will Herring and Martez Wilson, a rookie who made his first NFL start against the Texans. Coach Sean Payton did not address any of the new injuries after the game or during his weekly news conference on Monday, but will issue an injury report after the team returns to practice Wednesday.

In addition to putting Hartley on IR, the Saints waived defensive tackle Mitch King, a first-year player who recorded three tackles as a reserve in the team’s first three regular-season games.

Loomis also confirmed the team had signed veteran NFL tackle Pat McQuistan and re-signed linebacker Ramon Humber to fill the two open spots on the 53-man active roster.

McQuistan, a 6-foot-6, 315-pounder, was a seventh-round draft pick of the Dallas Cowboys in 2006. He saw action in 40 games with the Cowboys from 2006-09 with no starts, but started eight of 16 games last season for the Miami Dolphins.

McQuistan is expected to be the backup for second-year pro Charles Brown, a 2010 second-round draft pick who’ll likely be penciled into the starting lineup if Strief is sidelined for any length of time.

A three-year veteran, Humber played primarily on special teams after being signed by the Saints late in the 2010 season but was waived on Sept. 5 when the team had to sign an extra tight end to the roster.

The Saints also made a practice squad move Tuesday, releasing quarterback Sean Canfield and signing defensive tackle Swanson Miller. The signing of Miller, who was with the team in training camp, gives them some depth at the position for practice.

With Hartley sidelined, the Saints will go with 41-year-old John Kasay for the rest of the season.

Kasay, a 20-year veteran who was brought in when Hartley was hurt, missed his first fieldgoal attempt and first extra-point try in the Saints’ final preseason game, but hasn’t misfired since. In the first three regular-season games, he’s 6-of-6 in field goal tries and has made all 10 of his PATs.
