The Saints signed Holtz to their practice squad Wednesday, Aaron Wilson of ProFootballNetwork.com reports.
Holtz had seen action in each of New Orleans' contests since Week 4 before he was waived Saturday. He'll now return to the organization as a member of the team's practice squad. Holtz has been a non-factor as a pass catcher throughout most of his NFL career -- he's played in 35 games over the past three campaigns but has seen only one target and hasn't recorded a catch.
