Donovan McNabb will have surgery for a sports hernia and is expected to miss the rest of the season, another crushing blow for a team that had hoped to return to the Super Bowl. All-Pro cornerback Lito Sheppard also appears out for the season with a sprained ankle that will require surgery. Monday's announcements came one day after the reigning NFC champions fell to 4-6 with their fourth straight loss. The struggling Eagles also are without star receiver Terrell Owens, who was suspended four games and told not to return to the team on Nov. 7. McNabb didn't play in Sunday's 27-17 loss to the New York Giants after he re-injured his groin while trying to tackle Cowboys safety Roy Williams following an interception last Monday night. Williams returned it 46 yards for a touchdown with 2:43 left to lead Dallas to a 21-20 comeback victory over the Eagles.
