Stop us if you’ve heard this one before. The Saints are signing Khalif Barnes to the roster, as Herbie Teope of The Times-Picayune tweets. 
Today’s deal marks the fourth time that New Orleans has signed Barnes to the roster since Aug. 30. Barnes’ most recent stint on the 53-man roster ended about two weeks ago when the Saints bumped him for Joe Callahan. He’s back now, but if recent history is any indication, he might not be around for long. For his career, the 34-year-old has 151 appearances and 117 starts to his name, but he hasn’t taken the field yet this season.
The Saints freed up a spot for Barnes on Tuesday when they dropped defensive end Chris McCain.
