Lions injury updates on Kerby Joseph, Damone Clark, Thomas Harper

Detroit Lions safety Kerby Joseph remains sidelined with a personal matter, while coach Dan Campbell remains hopeful about his return this fall. Joseph, who missed most of last season due to a degenerative knee condition, has not participated in practices since mid-August for undisclosed personal reasons. Although he participated in rigorous workouts during the initial days of training camp, expressing optimism about his comeback, it appears unlikely he will be ready for the start of the regular season.

The Lions coach stated that players on the PUP (Physically Unable to Perform) list must miss at least the first four games.

Additionally, Lions safety Thomas Harper is grappling with an ankle injury that might sideline him for this week's preseason finale against the Indianapolis Colts. Furthermore, veteran linebacker Damone Clark's preseason is effectively over following an injury he sustained early in training camp. The Lions signed Clark as a backup linebacker and special teams contributor, but he now faces the possibility of starting the season on injured reserve.

Campbell confirmed Clark's indefinite absence from preseason activities, emphasizing that the injury was significant enough to warrant such a status.
