The Colts have promoted rookie linebacker Trevor Bates from the practice squad to the active roster.
The Colts drafted Bates in the seventh round last April. He went through training camp and preseason with the team before being released during the 53-man roster cutdown and signed to the practice squad.
Earlier in the day, the Colts announced that cornerback Antonio Cromartie and linebacker Sio Moore were released.
The Colts also announced that safety Lee Hightower has been brought back to the practice squad.
