LOS ANGELES -- Testing showed that Los Angeles Rams wide receiver Cooper Kupp suffered a high right ankle sprain in Sunday's loss to the Arizona Cardinals, a source told ESPN's Adam Schefter on Monday.
There was no immediate word on how much time the star receiver will miss.
After Sunday's game, Rams coach Sean McVay said the injury "didn't look good" and "didn't sound good."
Kupp left the Rams' Week 10 loss in the fourth quarter after injuring the ankle while attempting to catch a pass from quarterback John Wolford.
