The Rams do not believe the injury is a torn ACL, but Nacua will undergo an MRI Monday to confirm.
Puka Nacua went down with a knee injury on the Rams' final offensive snap of Sunday's 20-13 win over the Commanders. The All-Pro wide receiver caught a short pass with about 90 seconds left at Northwest Stadium and was tackled well short of the line to gain.
Nothing appeared to go wrong in the moment. Nacua popped back up and walked off the field normally after the tackle. Still, the team held him out the rest of the way as a precaution.
According to ESPN's Adam Schefter, the Rams do not believe Nacua suffered a torn ACL, though the exact nature of the injury remains unclear. He is set to undergo an MRI on Monday to determine the severity and how much time, if any, he might miss.
For a Rams team that has already dealt with its share of injury trouble this season, losing Nacua for any real stretch would sting. He has been one of the team's most productive weapons, and Los Angeles will be watching Monday's imaging results closely before figuring out next steps.
