The fifth-round pick hasn't practiced or played because of the injury. He was put on a non-football injury list and will get three weeks to practice before the Bengals have to decide whether to activate him. The Bengals want to develop him as a backup to Andy Dalton.
The Bengals also signed linebacker Terrell Manning to the practice squad on Tuesday and released rookie linebacker Justin Jackson, who had been on the squad since Nov. 3. Manning played in three games for the Bears this season and was waived on Nov. 11.
