KANSAS CITY, Mo. (AP) — Chiefs coach Andy Reid says running back Jamaal Charles is “a stretch” to play in their season opener against the San Diego Chargers following surgery last season to repair the ACL in his right knee.

Reid acknowledged Monday that the four-time Pro Bowl selection is still not ready for game action, even though he’s been practicing for several weeks. Charles did not play in any of the preseason games.

The Chiefs kept Knile Davis as their third running back behind Charcandrick West and Spencer Ware over the weekend, giving them insurance if Charles is unavailable. The trio filled in quite admirably when Charles was hurt in a Week 5 loss to the Chicago Bears.
