Carolina worked out Williams (hip) on Wednesday, Alex Zietlow of The Charlotte Observer reports.
Analysis:Williams was with the Buccaneers during training camp before they cut him prior to their regular-season opener with a hip injury, but he's now evidently back in football shape following Week 5. The Panthers recently placed Jaycee Horn (quadriceps) and Mike Jackson (groin) on their injured reserve list, so it makes some sense that they're looking into adding some organizational depth in the secondary.
