Rams All-Pro receiver Puka Nacua suffered a knee injury on the team's final offensive snap Sunday against the Commanders and will undergo an MRI on Monday to determine the extent of the injury, sources told ESPN's Adam Schefter and NFL Network's Mike Garafolo.
The Rams do not believe Nacua suffered a torn ACL, but the imaging Monday will tell more.
Nacua finished Sunday's 20-13 win in Landover, Maryland, with 14 catches for 150 yards and a touchdown. He was targeted 19 times by Matthew Stafford.
