Running back Marion Barber did not practice Wednesday and it appears unlikely the former Cowboys running back will play Sunday when the Bears open the regular season against the Atlanta Falcons at Soldier Field.
Barber, who rushed for 104 yards on 20 carries in the first two preseason games, suffered a calf injury in the first half against the Tennessee Titans on Aug. 27 and has not practiced or played since.
''We're running out of time a little bit for Marion,'' coach Lovie Smith said. ''But he's feeling a little better. So hopefully we'll be able to get him on the field before long.''
Linebacker Lance Briggs (knee), tight end Kellen Davis (back), long-snapper Pat Mannelly (calf), running back Kahlil Bell (knee) and safeties Craig Steltz (hip) and Chris Conte (head) all had ''full participation'' in practice.
Defensive tackle Anthony Adams (calf), wide receiver Sam Hurd (ankle) and defensive end Corey Wootton (knee) were limited.
Smith said the team is working hard and on target for Sunday's opener.
''We'll get back on the football field tomorrow. Hopefully we'll get a little bit better,'' he said. ''We're not ready for Atlanta yet. But we have a couple more days.''
