Marlon Mack (questionable, hamstring) is not expected to play Week 4 against the Texans.
This is the way Mack had been trending after the Colts promoted Jeremy McNichols from the practice squad. Mack got in some limited practice this week, so he looks on track to return in Week 5. Jordan Wilkins and Nyheim Hines will continue to form a committee against Houston.
