Mack (ankle) is listed as active for Sunday night's game against the Chiefs.
Mack, who was forced out of Week 4's loss to the Raiders, will thus give it a go after practicing fully Friday and evidently progressing favorably through pre-game warm-ups in advance of Sunday night's contest. As long as he avoids any setbacks, Mack is in line to head the Colts' Week 5 backfield, with Nyheim Hines and Jordan Wilkins on hand to serve in change-of pace/complementary roles.
