Delhomme hasn't been able to play or practice since suffering
ligament damage in his right thumb in Carolina's loss to
Philadelphia on Dec. 4. He tried to throw on the side before
Friday's practice, but had trouble gripping the ball.
Delhomme had his streak of 66 straight starts snapped last
Sunday in a loss to the New York Giants. Weinke threw for a
team-record 423 yards, but also had three interceptions.
The Steelers are without star safety Troy Polamalu for a third straight game.
