Kirkwood signed with the Saints' practice squad Wednesday, Mike Triplett of NewOrleans.Football reports.
Kirkwood will return to the Saints organization, where he appeared in nine games between 2018 and 2019, joining their practice unit. With Michael Thomas (toe), Jarvis Landry (foot) and Tre'Quan Smith (concussion) all banged up, it's possible that Kirkwood could be elevated to the active roster for Sunday's matchup with the Vikings in London.
