Bengals OG Jacob Bell announced his retirement from football.
A source tells Profootballtalk that Bell "simply lost the desire to play." The 31-year-old started 100-of-109 career games with the Titans and Rams before signing with the Bengals last month. With first-rounder Kevin Zeitler slated for a starting job, Bell was headed for a reserve role in Cincinnati. Bell's effectiveness fell off precipitously in St. Louis last season.
