Jones is feared to have suffered a torn right Achilles that will require surgery, but confirmation will come Monday, Mike Chappell of Fox 59 News Indianapolis reports.
Jones suffered a non-contact lower-leg injury in the first quarter of Sunday's 36-19 loss to Jacksonville, and he is now likely slated to miss the remainder of the season as a result. The quarterback was in the midst of a resurgent campaign with Indianapolis, but it unfortunately appears headed toward a premature end. Riley Leonard replaced Jones at quarterback in Week 14, but Anthony Richardson (orbital) could be in the picture as well to start for the Colts when/if he's able to return to action.
