Rivers rushed twice for nine yards during Sunday's 27-24 victory against San Francisco.
Kyren Williams (24-89-2 rushing line Sunday) is locked in as the starter for the Rams, but Rivers continued to work as the backup. The third-year pro converted a pivotal fourth down on a fake punt, keeping alive a drive that ended in a receiving touchdown for Williams. Notably, third-round rookie Blake Corum didn't take a snap on offense for the second time in three games, meaning Rivers seems firmly locked in as the backup to Williams, at least for now. Rivers likely will continue to have a limited role in the offense in a Week 4 contest against the Bears.
