The Bears announced they had signed the veteran cornerback to a one-year deal, giving them some depth in the secondary.
Porter was released by Washington earlier this offseason, a day after coach Jay Gruden said he had “flight issues” which kept him from the first day of OTAs.
Porter has also played for the Saints and Raiders, and spent a year with new Bears coach John Fox in Denver in 2012.
The Bears are thin there, and Porter could end up playing significant snaps there, which he wasn’t going to do in Washington.
