Rams' Saffold injured in weight room
Saffold is likely to need surgery after an MRI confirmed he tore a pectoral muscle while working out Friday.
Rams coach Steve Spagnuolo remained philosophical.
"Moving parts, even within the game, it happens," he said. "Coaches step up, get the next guy in there ready to go and away we go."
LeVoir had stepped in for Saffold during last Sunday's 13-12 win against the Browns.
