The Indianapolis Colts will enter the season with Marlon Mack as their No. 1 running back.
Mack and Jonathan Taylor were expected to battle for the starting job in camp.
"Marlon's a starter," Frank Reich said. "Marlon's earned it. He's had a couple of really good years for us. But we're going to continue to take the same approach that we have, where it's week in and week out, hot hand, all those things."
Mack rushed for 1,000 yards for Indianapolis last season, finishing 11th in the league while averaging 4.4 yards per carry.
