49ers-Titans inactives: Ahkello Witherspoon active, Greg Mabin inactive

The San Francisco 49ers and Tennessee Titans have announced their inactives for Week 15. The good news is that cornerback Ahkello Witherspoon is active. He suffered a knee injury last week against the Houston Texans, and Kyle Shanahan said he would be a game-time decision.

Cornerbakc Greg Mabin is inactive after suffering a calf injury in practice this week. He was expected to push Dontae Johnson for playing time, but the injury means Johnson will get the start and the bulk of the snaps opposite Witherspoon.

Aaron Lynch and Tank Carradine are active this week, the second straight week we will see them out there. The Titans are better running the ball than passing, so this is a little bit of a surprise. I would have expected one or more of Leger Douzable, D.J. Jones, and Ronald Blair to be active, but it is not to be.

49ers inactives: WR Max McCaffrey, DB Greg Mabin, DB Antone Exum Jr., LB Pita Taumoepenu, DL Leger Douzable, DL D.J. Jones, DL Ronald Blair

Titans inactives: QB Brandon Weeden, CB Kalan Reed, DB Curtis Riley, LB Josh Carraway, OL Corey Levin, WR Harry Douglas, LB Derrick Morgan
