Colts head coach Shane Steichen said that Richardson (oblique) is in line to practice fully Wednesday, Stephen Holder of ESPN.com reports.
Assuming Richardson does indeed log a full session Wednesday, he'll be one step closer to returning to action Sunday against the Dolphins. Steichen said Monday that he anticipates that Richardson -- who has missed the Colts' past two games -- will return to the starting role this weekend. In Richardson's absence, veteran signal-caller Joe Flacco helmed the offense, leading the Colts to a narrow loss to the Jaguars and a win over the Titans.
