Kupp is expected to be day-to-day with an ankle sprain, Ian Rapoport of NFL Network reports.
Kupp picked up the ankle injury late in Sunday's loss to the 49ers, but he appears to have avoided a significant issue. The superstar wideout's participation during practices ahead of Week 9 should provide further clarity on Kupp's availability, but the Rams likely will be extremely cautious with him moving forward.
