What It Means:

Perine was officially designated to return from injured reserve earlier in the week, getting in his first practice reps in over three weeks. However, the team still thinks he needs to do more before officially suiting up, so he'll stay on the IR for at least one more game. With Perine sidelined against the Los Angeles Rams, Frank Gore and Ty Johnson figure to handle the bulk of the backfield work once again.

The Rams currently rank 2nd in the NFL in adjusted net expected points allowed per run play.
