ARLINGTON, Texas (AP) - Green Bay Packers cornerback Charles Woodson was knocked out of the Super Bowl with an injured collarbone, and the team said he will not return.
The Packers also went into halftime Sunday night without cornerback Sam Shields, who injured a shoulder, while safety Nick Collins went to the locker room early to receive intravenous fluids.
Shields and Collins were both expected to return in the second half against the Pittsburgh Steelers.
Woodson appeared to injure his left collarbone in the second quarter. The injuries to him and Shields left the Packers vulnerable on a scoring drive by Pittsburgh that cut Green Bay's lead to 21-10 at the half.
Both teams lost wide receivers to injuries early, as the Steelers' Emmanuel Sanders left the game with a foot injury and the Packers' Donald Driver went to the locker room with an ankle injury.
X-rays were negative on Driver's ankle, but his return remained questionable. Sanders left with a foot injury and the team said he would not return after making a 13-yard catch early in the second quarter. He was taken off the field on a cart.
Driver's leg buckled on a hard hit by Pittsburgh's James Farrior and James Harrison in the second quarter.
Steelers cornerback Bryant McFadden injured a hip in the first quarter but was able to return.
Offensive tackle Flozell Adams injured his shoulder in the opening quarter when teammate Chris Kemoeatu slammed into his back during Collins' 37-yard interception return for a touchdown that gave Green Bay a 14-0 lead with 3:20 remaining. Adams was replaced by Trai Essex at right tackle for a few plays before returning to start the second quarter.
