Cincinnati placed Kirkland on its practice squad injured list Monday with a wrist injury.
Kirkland signed with Cincinnati this spring as an undrafted free agent out of Washington, but he was unable to make the team's 53-man roster out of training camp. However, he was able to earn a spot on the team's practice squad, where he's remained since Aug. 30. After being placed on the injured list, he won't be eligible for elevation to the active roster for any of Cincinnati's next four games.
