It's another significant setback for a player who has yet to get into a game.
The Bengals drafted him in the third round out of Nevada in 2011. He injured a foot during the preseason, then came down with an illness and was inactive for all 16 regular season games and a playoff loss to Houston. The Bengals also were disappointed with his progress in practice.
Moch can participate in Cincinnati's offseason workouts, training camp and preseason games. Once the season starts, he won't be allowed to be with the team for the first four weeks.
