Niners cornerback Ahkello Witherspoon will start today against the Titans at Levi’s Stadium after he was listed as questionable with a sprained knee he sustained in last week’s win at Houston.
Meanwhile, backup cornerback Greg Mabin is inactive because of a calf injury he sustained in practice this week. On Saturday, the 49ers promoted corner Tyvis Powell from the practice squad due to their injuries at the position. Leon Hall will presumably serve as the primary backup today.
Witherspoon will start alongside Dontae Johnson, who was benched last week after he committed three penalties while struggling to cover Texans wide receiver DeAndre Hopkins.
