Robinson (concussion) has made the Colts' 53-man roster and would enter Week 1 as the backup to Frank Gore with Dan Herron likely out with a shoulder injury, Indy Sports Central reports.

EDGE Analysis

Robinson could miss Week 1 as well as he'll need to prove he's healthy after suffering a concussion in the preseason. When Robinson does return, he'll enter the season as the No. 3 running back with the release of Zurlon Tipton. Robinson showed enough in the preseason it wouldn't be a surprise if he overtook Herron as the backup at some point.
