The Saints signed Dixon to the team's practice squad Wednesday, Katherine Terrell of ESPN.com reports.
The rookie wide receiver failed to make the Saints' final roster Tuesday, but he figures to serve as a depth option should any member of the team's WR corps miss any time. Dixon recorded a team-high four receptions and 33 receiving yards during New Orleans' preseason opener, but he was otherwise quiet throughout the team's final two exhibitions, catching just one pass for five yards.
