David Garrard was designated as the third, emergency quarterback.
Haynesworth hurt his hamstring chasing David Carr late in last week's 20-7 win over Carolina in what had been his best game as a professional. He had a career-high three sacks.
The Titans also deactivated defensive end Travis LaBoy, who suffered a concussion against Carolina. LaBoy is tied with Haynesworth and Kyle Vanden Bosch with a team-high five sacks. Running back Chris Brown missed a fourth straight game as he recovers from a sprained left ankle.
That meant another game for rookie Chris Henry, who appealed his four-game suspension for a positive test under the NFL's banned substances list last Wednesday. Rookie punt returner Chris Davis also was deactivated.
The Jaguars deactivated receiver Matt Jones, who was not on the injury report this week, and cornerback Aaron Glenn and offensive lineman Dennis Norman. Maurice Williams started at right guard with
Chris Naeole out for the season with a torn quadriceps tendon.
