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. He will miss the rest of the season.
Witherspoon injured his knee this past Sunday during the first quarter of the 49ers’ 26-23 overtime victory against the Seattle Seahawks. Witherspoon was defending a run play. He chased Seahawks running back Chris Carson to the sideline, planted awkwardly on his right leg and collapsed.
For a few minutes, Witherspoon lay on the ground in agony. Seahawks quarterback Russell Wilson walked over to Witherspoon to check on him, and players from both the 49ers and Seahawks knelt on the grass out of respect for a potentially serious injury to a football comrade.
Luckily for Witherspoon, his injury isn’t serious.
Still, Shanahan sounded disappointed Monday.
“Wish he could’ve finished these last two games,” Shanahan said. “I think he definitely was finishing (the season) better than he started. His story is not written yet. He’s got to improve. Hopefully, he’ll come back here ready to go next year and take off the way he finished.”
Witherspoon, 23, was a third-round pick in 2017. He started nine games as a rookie last season, intercepted two passes and showed promise. The 49ers thought he was an ascending talent, so they handed him a starting job for 2018. Didn’t make him earn it or compete for it during training camp.
But, during the regular season, Witherspoon regressed and seemed to lose confidence. He intercepted zero passes, got benched once, committed 10 penalties (three were declined) and gave up six touchdown catches. To Witherspoon’s credit, he didn’t give up any touchdown catches the past four games, although he did commit four penalties.
