Cornerback Aaron Ross and safety Gibril Wilson will not play for the New York Giants against the Chicago Bears on Sunday because of injuries. Wilson, Ross, halfback Brandon Jacobs and receiver Steve Smith were left home Saturday when the Giants flew to Chicago. Ross, the Giants' first-round draft pick, aggravated a hamstring injury in last weekend's loss to Minnesota and did not practice all week. Gibril missed practice on Thursday and Friday with a knee injury. Kevin Dockery, who replaced Ross for most of the second half and played well, will start. Rookie Michael Johnson is expected to fill in for Wilson. Johnson started a game earlier this season when safety James Butler was sidelined.
