                     === 49ers' Smith to seek treatment ===
 San  Francisco, CA  (Sports Network) - The San Francisco 49ers announced after
 Sunday's  loss  to the Indianapolis  Colts that outside linebacker Aldon Smith
 will be taking an indefinite leave of absence from the team to seek help for a
 substance-abuse problem.
 Smith was arrested on charges of driving under the influence and possession of
 marijuana  after  crashing his car  in San  Jose's Silver Creek district early
 Friday  morning,  though he  played in  Sunday's 27-7 defeat  to the Colts and
 recorded five tackles.
 49ers  CEO Jed  York said  following  the game  that  Smith will  not play  in
 Thursday's matchup at St. Louis and there is no timetable for his return.
 "We  are very  fortunate that  nobody got  hurt, Aldon  included, and  anybody
 else,"  said York in reguards to Friday's incident. "We want to make sure that
 Aldon is never in a position like this again."
 Smith  has  been involved in a  few off-field issues during his three-year NFL
 career.  The  All-Pro pass  rusher was  arrested on a  previous 2012 charge in
 Miami in January of 2012, and more recently was named in two lawsuits stemming
 from  a house party  he hosted in June of last year. He was reportedly stabbed
 at the party.
 "First  off,  I wanted to apologize  to the team, the organization, my family,
 everybody  that I let down," said Smith after Sunday's game. "I also wanted to
 let it be known that this is a problem. It's something I will get fixed, and I
 will do everything in my power to make sure that this never happens again."
 York  also admitted  that both he and  Niners head coach Jim Harbaugh made the
 decision to allow Smith to play in Sunday's contest.
 On the field, Smith has been one of the NFL's premier pass rushers since being
 taken  by  San Francisco with  the seventh overall pick  of the 2011 draft. He
 notched  14  sacks during his rookie  season, then ranked second in the league
 with  19 1/2 sacks last year while helping the 49ers to an appearance in Super
 Bowl XLVII.
