Chicago Bears on Monday released veteran cornerback Tracy Porter. Porter who is 30 years old had two interceptions last season, playing the majority of the season with a knee injury. Porter played in all 16 games last season, with his only missed start coming in Week 17 because he overslept and arrived to U.S. Bank Stadium late. Porter joined the Bears on a one-year deal at the veteran’s minimum in summer of 2015. His emergence that season earned him a three-year deal last March. The Bears have signed four cornerbacks since the start of free agency March 9. This offseason, the Bears signed Marcus Cooper and Prince Amukamara as their new top cornerbacks, then added B.W. Webb for depth last week. Tracy Porter was consummate pro on and off the field. Tough business.
