Running back Clinton Portis and cornerback Shawn Springs didn't practice Tuesday, and their availability for Monday night's regular-season opener against Minnesota was uncertain. Portis, who partially dislocated his shoulder in the preseason opener against Cincinnati, was the only player not on the field at the start of the workout but arrived to watch before it was over. Springs, recovering from abdomen surgery, and backup defensive end Renaldo Wynn (sprained ankle) also watched from the sidelines.
