Richardson, for whom the Colts gave up a first-round draft pick in September 2013, is inactive for Sunday's AFC divisional playoff game against the Denver Broncos.
The Colts acquired Richardson from Cleveland with the idea of teaming him with quarterback Andrew Luck for years to come. Richardson, the No. 3 overall pick in 2012, lost his starting job to Donald Brown late in the 2013 season.
Richardson regained the job this season but lost it toDaniel "Boom" Herronin Week 16. Richardson was the third running back behind Herron andZurlon Tipton in the wild-card playoff game against Cincinnati. Richardson played only one snap against the Bengals.
Richardson spent time practicing with special teams last week. He has rushed for only 977 yards in 29 games with the Colts.
