Rivers rushed six times for 31 yards and returned two kicks for 31 yards during Saturday's 31-17 preseason loss to the Chargers.
Competing to be the third running back on the Rams' roster alongside Zach Evans and Royce Freeman, Rivers started the game and ripped off a team-high 15-yard rush that was part of a lengthy second-quarter touchdown drive. While Rivers didn't get involved in the passing game, his kick return abilities were also on display, a skill that combined with his familiarity with the offense might give him the edge as a reserve behind Cam Akers and Kyren Williams.
