            === Chiefs remain perfect with win over Buffalo ===
 Orchard  Park,  NY ( -  The Kansas  City Chiefs' quest for a
 perfect  season has  remained intact. And once again, the team has its defense
 to thank for it.
 Sean  Smith came up with a tide-turning 100-yard interception return touchdown
 of  Jeff Tuel in the third quarter, and Tamba Hali took a fumble back 11 yards
 for  a go-ahead  score in the fourth  as the Chiefs rallied past the banged-up
 Buffalo Bills, 23-13, at Ralph Wilson Stadium.
 Ryan Succop kicked three critical field goals to help Kansas City (9-0) remain
 unbeaten  despite  being outgained by a  470-210 margin in total yards. Jamaal
 Charles added 90 yards on 17 carries in the victory.
 Tuel,  making his first NFL start with quarterbacks E.J. Manuel and Thad Lewis
 both  out with  injuries,  hit fellow  rookie Marquis  Goodwin  for a  59-yard
 touchdown  in the  opening quarter but struggled thereafter against the fierce
 Kansas  City defense.  The undrafted free agent finished with 229 yards on 18-
 of-39  passing and  threw a  pair of  costly interceptions,  none bigger  than
 Smith's  pick that tied the game at 10-10 after the Bills were on the verge of
 building a two-score lead.
 "We  never panic, not even for one second," said Chiefs safety Kendrick Lewis,
 who  had the other interception of Tuel. "We always go in knowing that someone
 on  our defense is  going to make a play. That's how we believe in each other.
 No matter who it may be, someone will come up with a play."
 C.J.  Spiller returned  from a  sprained  ankle to  rack  up 116  yards on  12
 attempts  for Buffalo  (3-6), with Fred Jackson totaling 77 yards on 16 rushes
 in the loss.
 The  Bills owned  a 10-3 edge at  halftime and were threatening for more after
 Spiller  ripped  off a 61-yard run  to the Kansas  City 19 on the initial play
 from  scrimmage of the third quarter. A pass interference call later created a
 1st-and-goal situation from the one, but Jackson was stuffed on a pair of runs
 to bring about third down.
 Tuel  then  misread the coverage while  under pressure, and his floater landed
 right  into  the hands  of Smith, who  raced down the  sideline for a 100-yard
 touchdown that sent the home crowd into a state of disbelief.
 "It  was like  Christmas. You  know, you  go downstairs  as a  little kid  and
 there's a big box right there. That's how I felt," said Smith of the play. "If
 [Tuel]  threw it right to me, the main thing I just wanted to do was focus and
 catch the ball. Because I knew once I caught it that no one was catching me."
 The Chiefs also stopped Buffalo on downs with the game still tied later in the
 third  quarter  to take over  at their own  37-yard line. A 20-yard connection
 from quarterback Alex Smith to Anthony Fasano followed by Charles' 12-yard run
 put Kansas City in position for Succop's 41-yard field goal, giving the Chiefs
 their first lead of the day with 3:57 left in the period.
 Buffalo  responded with  its best drive of the second half, a 12-play, 68-yard
 march  highlighted by Spiller's  25-yard gain on a screen toss that set up Dan
 Carpenter's 30-yard kick that knotted the score entering the fourth quarter.
 The  Bills'  next possession  ended in  disaster, however.  T.J. Graham made a
 catch  over the  middle but had the  ball knocked loose by Marcus Cooper, with
 Hali  alertly scooping  up the fumble deep in Buffalo territory and running in
 untouched with 12:47 to play.
 "He  made  a good  defensive play," said  Graham of Cooper.  "I had [the ball]
 tucked,  but it could  happen to anybody. We've got to come out and hold on to
 the ball and make plays for [the defense]."
 Buffalo  failed to  mount a charge the  rest of the way. Goodwin couldn't come
 down  with  a would-be 40-yard  catch near  midfield with around seven minutes
 remaining, and the Bills ultimately punted the ball away.
 With Charles handling the bulk of the work, the Chiefs moved 32 yards in seven
 plays  before Succop made it a 10-point spread by booting home a 39-yard field
 goal with 4:16 on the clock.
 Tuel  was able  to get the Bills to  the Kansas City 35 on the ensuing series,
 but overthrew Stevie Johnson on fourth down and the Chiefs ran out the clock.
 Tuel  was  impressive early  on, hitting  on 5-of-7 passes  for 112 yards over
 Buffalo's  first two  drives. The  majority of  that yardage  came on  a well-
 thrown  deep ball that the lightning-fast Goodwin hauled in after blowing past
 the  Kansas City  secondary to give Buffalo  a 7-0 advantage late in the first
 The  Bills'  subsequent  offensive  trip  didn't go  as  well  for  the  young
 quarterback,  whose throw  sailed over the head of the 6-foot-7 Scott Chandler
 and was picked off by Kendrick Lewis at the Buffalo 41.
 Alex  Smith got  the Chiefs into scoring  range by evading a blitz and hitting
 Dwayne  Bowe for  a 6-yard  gain  on 3rd-and-4,  though Kansas  City wound  up
 settling  for  Succop's 27-yard  field goal when  Bills defensive back Nickell
 Robey's  big hit on a short catch by Dexter McCluster prevented another moving
 of the chains.
 Tuel  bounced back by leading a 14-play, 71-yard sequence that enabled Buffalo
 to  extend the margin,  getting help from a 29-yard burst from Spiller down to
 the  Chiefs' 16.  The Bills later had  a 1st-and-goal from the six, but Kansas
 City held to force Carpenter's 26-yard field goal with 1:47 left in the half.
