Atwell had three receptions off of four targets for 48 yards in Sunday's 41-10 loss to the Cardinals.
Atwell bounced back from a no-catch performance in Week 1, finishing as the Rams' second-leading receiver following Cooper Kupp's (ankle) early departure. With the team already down Puka Nacua (knee), Atwell could find himself in an increased role for Sunday's upcoming tilt against the 49ers.
