Also, cornerback DeAngelo Hall will be sidelined again with a sprained right knee, denying him a chance to face his old team.
Both players were ruled out by coach Jim Zorn on Friday.
Haynesworth missed two games with the gimpy ankle and then reinjured it in last week's loss to the New Orleans Saints. Hall will miss his third straight game with the ailing knee.
Fullback Mike Sellers was ruled out earlier in the week. Sellers received a severe thigh bruise in the New Orleans game and was hospitalized Sunday night.
