Coach Chuck Pagano said Rogers was released for ''conduct detrimental'' to the team. Safety Dewey McDonald was promoted from the practice squad to the active roster.
Rogers joined Indy (2-2) as a free agent in 2013 after acknowledging he had failed multiple drug tests at Tennessee. He eventually transferred to Tennessee Tech.
Indy also placed reinstated linebacker Robert Mathis on the reserve/non-football injury list.
