GEORGETOWN, Ky. (AP) The Cincinnati Bengals released offensive tackle John Jackson on Sunday.

The 37-year-old Jackson, who was the oldest player on the roster, had an angiogram early in training camp after two stress tests returned slightly abnormal results.

The angiogram found nothing wrong with his heart, and Jackson had been limited to individual workouts while he healed from the procedure.

Jackson was the backup to Richmond Webb at left tackle last season, and slid even deeper on the depth chart after the Bengals drafted tackle Levi Jones in the first round.

The 14-year veteran played in 203 games with Pittsburgh, San Diego and Cincinnati.
