Williams (knee) is participating in individual drills during the opening days of OTAs, Bill Voth of the Panthers' official site reports.

Williams is recovering from surgery to repair a torn MCL and dislocated patella in his right knee, an injury he suffered in Week 1 of last season. The Panthers felt good enough about Williams' ability to rebound by signing him to a one-year extension this offseason. The veteran's progress up to this point suggests he's nearing a return to the full participation.
