Mack (hand) has been ruled out for Sunday's game against the Titans, Mike Chappell of Fox 59 News Indianapolis reports.
This news is expected, as Mack broke his dominant ball-carrying hand Week 11. There's still no definitive timeline, but coach Frank Reich isn't shy about tipping his hand early in the week. During Week 12's loss to the Texans, Jonathan Williams served as a bell cow with Nyheim Hines rotating in. Williams had success, so the Colts may roll out the same game plan, though Jordan Wilkins should be healthy and ready to help out as well.
