The Saints re-signed three players in the team's first roster moves since coach Sean Payton returned from suspension in late January.
Safety Rafael Bush, tight end Michael Higgins and offensive guard Eric Olsen were all exclusive rights free agents.
Bush, who announced his signing via Twitter on Tuesday, was signed by New Orleans off of waivers from Denver just prior to the first week of the 2012 regular season.
Olsen turned into key contributor as the team's extra offensive lineman, seeing action in all 16 games while starting four.
Higgins has appeared in four games with the Saints and spent the final five weeks of 2012 on the active roster after spending the first 12 on the practice squad.
