The Colts confirmed Marlon Mack's season-ending Achilles tear Monday, putting Taylor in position for an expanded role going forward, Tom Pelissero of NFL Network reports.
Rather than beginning his career in a three-headed backfield by committee, Taylor now looks to be in prime position to emerge as Indianapolis' lead ball carrier, with Nyheim Hines handling a change-of-pace role. Taylor logged nine carries for 22 yards during Sunday's loss to the Jaguars while also adding six catches for 67 yards. The rookie second-round pick's explosive early down profile wasn't perfectly suited to a Week 1 tilt in which the Colts were forced to play catch-up, but he'll have a chance at a more favorable game script against the Vikings on Sunday.
