Jones won't play in the preseason, according to Jonathan Jones of CBSSports.com.
By all accounts, Jones' recovery from the torn right Achilles that he suffered in Week 14 last season has gone well, but the Colts will play it safe with their starting QB. Per Joel A. Erickson of The Indianapolis Star, Anthony Richardson will start Thursday's preseason opener against the Patriots and play the first half, while Riley Leonard will work in the second half, an arrangement that is in line to be reversed in the team's second exhibition tilt against Atlanta.
