Richardson has worked out for the Saints, ESPN's Mike Triplett reports.
With RB Khiry Robinson having suffered a fractured tibia, the Saints also took a look at Travaris Cadet. Given that the team has reportedly signed Tim Hightower, it doesn't look like Richardson will be headed to New Orleans, but a weekend filled with backfield injuries has led to a number of free agent running backs -- including the former No. 3 overall pick -- drawing interest in advance of Week 9.
