From the Saints Wire (LINK):
A season in the XFL was good for Niko Lalos. He used the opportunity to develop his craft and pick up some new tricks, which he used to bag a couple of sacks in the New Orleans Saints’ preseason. But it wasn’t enough for him to make it through roster cuts. NewOrleans.Football’s Brooke Kirchhofer reports that the Saints have waived Lalos, making him a top candidate to return on their practice squad. That’s where he was for much of last season.
