Overview

• Head coach Jim Harbaugh confirmed Johnston sustained a concussion following a helmet-to-helmet hit by Rams safety Tanner Ingle.

• He later moved his arms and legs, spoke with doctors on the sideline, and walked under his own power before being taken to a hospital.
• Rookies KeAndre Lambert-Smith and Tre Harris have received increased first-team snaps as short-term depth in the receiver corps.
• The team has not provided a recovery timeline and is awaiting test results under the NFL’s concussion protocol.
