Williams still is facing a four-game suspension at the start of the regular season, although he will be allowed to practice in the meantime and take part in the preseason games.
In other news:
--The Dolphins signed two draft picks, third-round choice Channing Crowder and fifth-round selection Anthony Alabi. Both players got four-year contracts. That leaves three draft picks unsigned, first-round pick Ronnie Brown, second-round pick Matt Roth and seventh-round pick Kevin Vickerson. Brown isn't expected to be signed for at least a few days, meaning he will miss the start of training camp.
-- The Dolphins swapped tight ends on the roster, signing Lorenzo Diamond formerly of the Arizona Cardinals and waiving rookie free agent Joe Munson.
-- The Dolphins have announced that the Nov. 13 home game against the New England Patriots is a sellout.
