The Lions placed Williams (knee) on the active/non-football injury list Sunday.
As expected, Williams won't be ready for the start of training camp and instead will continue his rehab from the ACL surgery he had in January. After investing the 12th overall pick on the wideout, the Lions likely will continue to exercise the utmost caution, but when the rookie eventually is cleared, he'll form a potentially dynamic WR trio with Amon-Ra St. Brown and DJ Chark.
