Kurt Warner was hospitalized with a concussion after the Rams lost to the New York Giants Sunday.

A CT scan and X-rays on his neck and head taken Sunday night were negative.

Coach Mike Martz said the two-time league MVP would return to St. Louis today.

Martz said the injury might have occurred in the first quarter of the 23-13 loss when Warner was sacked in the end zone and fumbled, with the ball recovered for a touchdown by the Giants.

“He didn’t seem the same after that,” Martz said. “A lot of times he didn’t seem to understand the plays we were calling from the sidelines.”

Warner complained of an upset stomach after the game and lay in the trainer’s room before Dr. Bernard Garfinkel, the team physician, made the diagnosis. Garfinkel said the concussion was “mild to moderate.”

The Packers lost two of their top receivers on the same drive in a 30-25 loss to the Vikings.

Pro Bowler Donald Driver strained his neck in a scary fall in the fourth quarter.

Driver was to be kept overnight in the hospital for further evaluation today. Barring a setback, his playing status is week-to-week, team doctor Patrick McKenzie said.

Shortly after Driver was hurt, the Packers’ other starting receiver, Robert Ferguson, tore ligaments in his right ankle and knee.
