Nacua will serve as the Rams' No. 3 wide receiver with Cooper Kupp (hamstring) ruled out for Sunday's contest against Seattle, Jourdan Rodrigue of The Atlantic reports.
The rookie fifth-round pick out of BYU will be thrust into a fairly significant role to start his career as one of the starting wideouts for the Rams along with Van Jefferson and Tutu Atwell. Nacua made his only appearance in the preseason count, posting three catches for 32 yards and a touchdown on five targets in a 34-17 loss to the Chargers on Aug. 12. Kupp's hamstring injury could be serious enough for him to begin the season on injured reserve, so Nacua's increased role could extend beyond this week.
