Driver, who never lost consciousness after the fourth-quarter injury, will stay in the hospital overnight and will be evaluated again Monday morning.
Driver's status will be listed as "week to week," according to the team.
The receiver suffered the injury when he jumped to attempt a catch of a Favre pass with about 8:40 remaining in the game. He got his hands on the ball and began to reel it in when he lost control of his descent and fell awkwardly on his arm, head and neck. He was down on the field for several minutes before he was immobilized and taken from the field on a stretcher as the crowd saluted him with a standing ovation.
