Jennings played five seasons in Chicago, after spending his first four years in the NFL with the Indianapolis Colts. The former second-round pick out of Georgia started 91 games during his nine-year career, racking up 461 total tackles, 20 interceptions and 78 pass breakups.
The 32-year-old signed a four-year contract extension following the 2013 season and still has one year of guaranteed money left on his deal. The Bears will be on the hook for $6.65 million this season, although his contract carries offsets, meaning if another team signs Jennings the Bears will only have to pay the difference in his new deal.
Jennings has been an integral part of Chicago's defense for six seasons but faded last year and struggled in training camp this year. He played well into the fourth quarter of last night's preseason game, so the writing was on the wall.
