Colts running back Trent Richardson was demoted to third-string running back during Indianapolis' wild-card win against the Bengals. Richardson received no touches and played just a snap in the second half.

The Colts said Richardson was behind Daniel Herron and Zurlon Tipton on the depth chart last week because he missed some practice time due to an illness. However, his role heading into Sunday's divisional playoff game against the Broncos remains uncertain.

"We’re going to evaluate the situation as we go through the week and we’ll know more as we go through the week," coach Chuck Pagano said, per ESPN.

Richardson has been a disappointment in Indianapolis since his acquisition in September 2013 from the Browns. Although, general manager Ryan Grigson doesn't regret acquiring the former first-round pick.

"When we made that trade it was a great shot in the arm," Grigson said during the radio interview earlier in the week. "We lost our starter. I felt like it was the right football move at that time. I’ll never back off that thought. I thought it was a no-brainer."
