SANTA CLARA — One young cornerback’s season ended this past Sunday, and another young cornerback’s season just began.
The 49ers announced Monday they will place second-year starting cornerback Ahkello Witherspoon on the Injured Reserve List with a sprained PCL (posterior cruciate ligament) in his right knee. And they will replace Witherspoon in the starting lineup with rookie cornerback Tarvarius Moore, who will make his first career start this Sunday against the Chicago Bears.
Witherspoon’s knee injury will “take a few weeks” to heal, according to head coach Kyle Shanahan. But the 49ers’ season will end in 12 days, so Witherspoon won’t return in time to play.
