The Colts signed Jones to their active roster Monday.
The Colts currently have T.J. Carrie (undisclosed) and Julian Blackmon (Achilles) on injured reserve, and Khari Willis (calf) exited the Week 8 loss to the Titans early, so they will add Jones to their active roster to add depth to their secondary. If Willis is unable to suit up in Week 9, George Odum will likely draw the start with Andrew Sendejo, as Jones operates as the primary backup.
