Peters missed all of training camp and preseason with a left foot injury. The earliest Peters can return is Oct. 28 at Philadelphia. He must sit out the first six games.
Peters, a third-round pick out of Kentucky in 2010, started 30 of his 31 games over the past two years. Peria Jerry is starting at nose tackle to replace Peters, who has 73 tackles, four sacks, one interception, one fumble recovery and three passes defensed in his career.
NFL teams have to reach the 75-man roster limit by Monday.
