Ratliff also missed the season opener last week against the New York Giants. Josh Brent will start again in Ratliff's place.
"He's making progress. He's getting better every day and trying to do more and more," coach Jason Garrett told the Dallas Morning News. "He's done a real good job with his treatment and his rehab. We're hopeful as it goes he'll get some work in practice and be back sooner rather than later."
Center Phil Costa will also miss Sunday's game with a back injury. He has had back problems since training camp and left the game against the Giants early. Ryan Cook, who replaced Costa, will start in his place against Seattle.
