He returned in '08 for the Cowboys, was out of the league again in '09 ... then made a solid comeback in 2010 with the Bengals, where he was named a First-Team All-Pro in 2014 and a Pro Bowler in 2015. After 8 seasons in Cincy, he finished his career in 2018 with the Broncos.
Pacman's retirement news comes on the heels of his arrest and guilty plea in an Indiana casino cheating case, in which he agreed to a short jail stint and serving a probation period that will bar him from drinking booze for a year and a half.
