Indianapolis suspended the running back for not telling the team he would be missing a walk-through. He missed the AFC title game because of the suspension and was set to miss one game next season as well. 

It was later reported that the suspension potentially could allow the Colts to void the final season of Richardson's contract without paying him more than $3 million in guaranteed money he was set to earn. That money is a focus of the grievance, according to PFT. 

Indianapolis was reportedly frustrated with Richardson due to his accessibility to the team and because he reportedly gained approximately 15 pounds during the season.

Richardson began the season as the Colts' starter but averaged just 3.3 yards per carry over 15 games and saw his role diminish later in the regular season, with Boom Herron seeing an increased workload.
