Marlon Mack (shoulder) ruled out for Week 3 by Colts

Indianapolis Colts running back Marlon Mack (shoulder) has been ruled out for Week 3.

What It Means:

Mack hurt his shoulder in the Week 2 loss to the Arizona Cardinals and was unable to practice on Thursday and Friday. The Colts will have Matt Jones active as the number-three back behind Frank Gore and Robert Turbin on Sunday.

After an impressive Week 1, where he totaled 42 yards and a touchdown, Mack regressed in Week 2, rushing 6 times for -3 yards versus the Arizona Cardinals.
