Kitselman left Sunday's training camp practice early due to a leg injury, Dave Birkett of the Detroit Free Press reports.
Kitselman signed with the Lions in mid-May as an undrafted free agent. He's competing for a depth spot on the team's 53-man roster by the time training camp wraps up, so he'll aim to return to practice and be ready for the Lions' preseason opener against the Bengals on Thursday, Aug. 13.
