No, this is not a re-post. The Saints are signing offensive lineman Khalif Barnes, according to Nick Underhill of The Advocate (on Twitter). To make room on the roster, cornerback Brian Dixon is being released. The Saints made this exact same transaction in reverse on Saturday. 
The 34-year-old Barnes has been yo-yo’d on and off of the Saints’ roster this year. After being cut on October 1st, Barnes apparently did not drift far from New Orleans. Coach Sean Payton said that Barnes was not in football shape in September, but his conditioning is presumably better now.
Dixon, a third-year UDFA out of Division II Northwest Missouri State, played in all 32 of New Orleans’ contests in 2014-15 as a backup. Given the way the Saints have been playing with the roster, it wouldn’t be a surprise to see him return in the near future.

Why would you let a DB go unless Breaux will be coming back after the bye?
