The Panthers traded a 5th round pick to the Chicago Bears for S Chris Harris, a 2-year pro (and former 6th round pick) from Louisiana-Monroe.

Harris started both safety positions with the Bears last year, and has 5 picks over 2 seasons.
The news is from Yahoo.

The article also mentions a right-knee injury to Salley, who had been working with the first team.

I don't know much about Harris, but hopefully he's able to help upgrade the defensive secondary.
