Joseph, the NFL's interceptions leader in 2024, hasn't played since Detroit's Week 6 date against Kansas City. The 6-foot, 210-pound safety injured his knee during Lions training camp, suffered a bone bruise in the same spot in a Week 4 win against the Cleveland Browns and is reportedly dealing with a cartilage issue that has made it too painful to play.

Though he would be eligible to return if Detroit advanced to the Divisional Round of the playoffs, the expectation is that Joseph's season is over and that he will pursue non-surgical options to help his knee this offseason, such as stem-cell therapy, according to the Detroit Free Press. Detroit also activated a starter to its 53-man roster.
