Miller exited Tuesday's practice alongside trainers with an apparent injury, Katherine Terrell of ESPN.com reports.
There's been no indication Miller is dealing with a serious injury, but his departure leaves just Audric Estime as the lone healthy running back behind Travis Etienne, as Alvin Kamara is still recovering from a sprained MCL in his knee. A third-round pick in 2023, Miller has appeared in just 21 career regular-season games, rushing 127 times for 497 yards (3.9 YPC) and three touchdowns.
