The Saints designated Williams (hamstring) for return from injured reserve Tuesday.
Williams was listed as a limited participant Monday on the Saints' initial Week 7 injury report, but because the report was merely an estimate, his 21-day evaluation window wasn't opened. The Saints held a walkthrough session Tuesday, and with Williams participating on a limited basis, the team now has three weeks to activate him from IR. Given that New Orleans is unlikely to hold a rigorous practice session Wednesday, the 28-year-old doesn't seem especially likely to be activated ahead of Thursday's game against the Jaguars. Instead, a return in Week 8 at Indianapolis is more realistic for Williams, who is expected to work in complementary fashion to Alvin Kamara as a short-yardage and early-down specialist.
