Kupp (oblique) was a limited participant in Thursday's practice, Curtis Crabtree of Sports Radio 950 KJR Seattle reports.
Coach Sean McVay has expressed confidence that Kupp will be available against the Seahawks on Sunday, but it's at least somewhat concerning to see the 27-year-old log back-to-back limited practices coming off a bye. He'll get one more opportunity to upgrade to full practice activity before the Rams designate him with an official injury tag.
