Rams head coach Sean McVay has ruled out Kupp (hamstring) for Sunday's season opener at Seattle, Sarah Barshop of ESPN.com reports.
After Kupp aggravated his hamstring injury last week, McVay called the wideout "day-to-day," which is exactly the same label offensive coordinator Mike LaFleur gave Kupp shortly after suffering the initial injury Aug. 1. With Kupp having now been confirmed as out for Week 1, he'll await word on his recent visit to a specialist in Minnesota to get a more precise prognosis. At least for the season opener, the Rams will roll with a receiver group of Van Jefferson, Tutu Atwell, Puka Nacua, Ben Skowronek and Demarcus Robinson.
