ST. LOUIS – I have arrived here for Thursday night's San Francisco 49ers-St. Louis Rams game, to predictable 49ers injury news.Both tight end Vernon Davis (hamstring) and linebacker Patrick Willis (groin) are listed as questionable for the game. I'd say Davis, who missed Sunday's loss to the Colts, is more likely to play than Willis, who was hurt in the third quarter. Davis practiced on a limited basis the past two days. Willis did not practice this week; he and defensive coordinator Vic Fangio nevertheless expressed hope he would play.
