Steve Young, still battling to recover from perhaps the worst of several concussions over the last three years, met with his neurologist yesterday and his football future appears increasingly uncertain. Young, 38, a two-time NFL MVP, wasn't cleared to play in Sunday's game after a day-long battery of tests at Stanford Medical School. "I really want to play again," Young said. "To me the most important thing is to get cleared by the doc and I've just got to keep working at that."

Subdued 49ers Coach Steve Mariucci said Young was still dealing with post-concussion symptoms of fatigue and wooziness 2 1/2 weeks after the damaging head blow.

MOORE UPDATE: Lions WR Herman Moore, who sprained a knee in the season opener in Seattle, is expected to play Sunday against the Vikings.

DAVIS SURGERY: Denver RB Terrell Davis underwent reconstructive surgery to repair a torn ligament in his right knee. He faces four to six months of rehabilitation.

DENT RETIRES: Chicago's Richard Dent will officially retire before the Bears' game Sunday against the Eagles. He'll serve as honorary captain, and a banner with his No. 95 will fly at Soldier Field for the rest of the year.
