SANTA CLARA, Calif. – Now that star pass-rusher Aldon Smith is out likely for about a month as he seeks treatment for a personal matter, where does that leave the San Francisco 49ers' defense?Smith is on the reserve/non-football-illness list. He can return when cleared by physicians; it is expected he'll be out about a month. The 49ers (1-2) play Jacksonville in London in Week 8, on Oct. 27; their bye week follows. Smith can come off the reserve list at any time -- something that is only allowed during the season if the player has substance-abuse issues.
