IRVING, Texas -- Dallas Cowboys defensive tackle Tyrone Crawford is questionable for Sunday's wild-card matchup against the Detroit Lions after not practicing Friday because of an illness.

Linebacker Rolando McClain missed last week's regular-season finale against the Washington Redskins because of an illness. Running back DeMarco Murray missed one day of practice last week because he was sick but played against the Redskins.

Linebacker Anthony Hitchens missed his third straight day of practice with a high right ankle sprain and is also listed as questionable. Right tackle Doug Free also did not practice for the third straight day because of a left ankle injury and is poised to miss his third straight game. Jermey Parnell has started six games in Free's absences due to foot and ankle injuries.

Defensive tackle Nick Hayden (shoulder) and safety C.J. Spillman (groin) returned to practice on a limited basis after missing the first two days of the work week. They are listed as probable, as are quarterback Tony Romo (back), Murray, McClain, guard Zack Martin (ankle), linebacker Bruce Carter (knee), safety Jeff Heath (thumb) and defensive tackle Josh Brent (calf).
