Porter, 29, has re-signed with Chicago, he confirmed on his Twitter account. The deal is for three years and $16.5 million, according to NFL Network’s Ian Rapoport.

Porter had 38 tackles, a team-high 22 pass breakups plus an interception and forced fumble in a bounce-back 2015 season after an injury-plagued 2014. The interception proved to be a heroic play in the Bears’ win over the Packers on Thanksgiving in Green Bay. He was routinely Chicago’s most consistent cornerback.
