Porter announced his retirement Friday, Luke Johnson of NOLA.com reports.

EDGE Analysis

Porter last played for the Bears in 2016, but he's best known for his pick-six that essentially clinched a win for the Saints in Super Bowl XLIV against the Colts. His career finished with 370 tackles, 2.5 sacks, 13 interceptions and 72 pass breakups.

Porter was waived by the Bears on Monday.

EDGE Analysis

Porter started 28 of his 30 games played after joining the Bears in 2015, combining to accumulate 83 tackles, 21 pass deflections and three interceptions over that span. Last year, the veteran battled through knee pain to feature in all 16 games, playing a prominent role in Kyle Fuller's season-long absence. With Chicago currently boasting over 10 cornerbacks on its roster ahead of the draft, however, the team has opted to cut bait with Porter, who will now look to latch on as a depth contributor elsewhere.

Porter tallied a pair of tackles in Sunday's 38-10 loss to the Vikings, and he ended the season with two interceptions, a forced fumble and 48 tackles.

EDGE Analysis

Porter was an absolute warrior this year, as he dealt with knee issues for most of the campaign, but he started 16 games for just the second time in his nine-year career. Unfortunately, he hasn't had more than two interceptions in a season since 2009, and his lack of playmaking ability will continue make him a marginal IDP option when he returns to the Bears for the second of a three-year deal he signed before the season.

Porter (knee) is active for Sunday's game against the Vikings, Rich Campbell of the Chicago Tribune reports.

EDGE Analysis

Porter was a limited participant in practice throughout the week, but may ultimately be able to play through the pain on Sunday. Fellow cornerback Bryce Callahan (hamstring) is also considered questionable, so Sherrick McManis could be in line for additional reps.
