Coach Ken Whisenhunt said Boldin was alert and was moving his extremities. He was taken to Mount Sinai Hospital in New York for what Whisenhunt said were precautionary reasons.

Boldin tried to catch a pass from Kurt Warner, but was hit in the back and then took a shot to his helmet from Eric Smith. Both Boldin and Smith fell to the turf, and Cardinals receiver Larry Fitzgerald immediately waved to the sideline for help.

Trainers ran out to check on Boldin, and soon the entire Cardinals team surrounded their teammate as the Giants Stadium crowd fell silent. Smith, also injured on the play, was able to get up after a few moments.

After being working on for several minutes, Boldin was immobilized and placed on a stretcher before he was carted off the field.

Boldin was talking to his teammates coming off the field and going into the locker room.

"He asked to get up and the doctors won't let him," Whisenhunt said.

Warner, who threw for 472 yards but had five turnovers in the game, said he went to Boldin's side and told him he loved him.

"It's a scary, scary part of the business," Warner said. "No matter how badly you play, you want to come out healthy."
