Overview
- On Sunday Lenoir was shaken up after colliding with linebacker Fred Warner while making a tackle and remained down before trainers helped him off the field.
- The 49ers announced Lenoir is being evaluated for a concussion after he was checked in the blue medical tent and taken to the locker room.
- Reports say Lenoir later returned to the game, but the formal concussion evaluation remains the primary medical determination.
- Lenoir's check comes with limited cornerback depth for the 49ers, who may rely on Renardo Green, Jack Jones and Upton Stout and could move Siran Neal back to corner for added coverage.
- Under NFL concussion protocol a sideline evaluation must be followed by additional testing before a player is cleared, and Lenoir's availability matters because he has registered five tackles through the first two games this season.
