The New Orleans Saints have placed KR Courtney Roby (head) on injured reserve. To take his place on the 53-man roster, the team signed WR Adrian Arrington off the practice squad.

With Roby gone for the rest of the season, the team will likely look toward WR Robert Meachem and RB Pierre Thomas to return kicks.

In other team news, the Saints signed DT Mitch King, CB Mark Parson and WR Andy Tanner to the practice squad. The team is now at the eight-man practice squad player limit.
