The Saints placed KR Courtney Roby on injured reserve Thursday with a concussion.
Roby sustained the concussion in the Saints' Week 14 31-13 win over the Rams. He was listed as probable for last Monday's game against the Falcons.
The seventh-year veteran averaged 23.8 yards on 33 kickoff returns. WR Adrian Arrington was promoted from the practice squad to replace Roby.
The way we see it
This is a blow to the Saints' special-teams unit. Roby gets the team good field position and RB Pierre Thomas will likely handle kickoff returns in Roby's absence. Roby also has 10 tackles and two fumble recoveries as part of coverage teams.
