Cardinals head coach Bruce Arians said running back Chris Johnson will start Sunday's game against the Rams, regardless of Andre Ellington's (knee) availability, Kent Somers of the Arizona Republic reports.
Andre Ellington (knee) will likely be limited to passing-down work for the most part, if he's even active for the game. Johnson thus figures to lead the Arizona backfield for a third straight week, but his Sunday matchup is much tougher than the last two. Johnson may stay ahead of Ellington even beyond Week 4, so the Arizona backfield once again bears close watching.
