Witten played despite being bothered this week by a sprained left foot sustained in Sunday's 7-6 victory over Washington.
The Raiders placed linebacker Jon Alston on injured reserve, ending his season after two concussions. Sam Williams replaced him in the starting lineup for the second consecutive game, and rookie Slade Norris was signed from the practice squad but was inactive.
Oakland defensive ends Richard Seymour (lower back strain) and Greg Ellis (knee, shoulder) were active. Ellis played the first 11 seasons of his career for Dallas before signing with Oakland this summer.
Cowboys safety Ken Hamlin (right ankle) and offensive tackle Marc Colombo (broken left leg) each missed their second straight game.
