In a defensive slug-fest, the two squads combined to score just 13 points, with Kansas City getting the only touchdown of the contest.
Here are six things that we learned from the Chiefs win over the Bears in Week 13.
Former Ole Miss star Dexter McCluster stole the show for KC in Week 13 against Chicago.
He had 107 yards from scrimmage, including an incredible Hail-Mary TD catch for the only touchdown in the game.
He showed the same explosiveness that the Chiefs brass saw in him when they decided to take him in the second round of the 2010 NFL Draft.
The Chiefs are now hoping that he can continue to provide a spark for their offense for the rest of this season.
The Chiefs defense had their second straight solid effort on Sunday.
The pass rush was on fire, sacking Bears' quarterback Caleb Hanie a total of seven times.
The pass coverage wasn't too bad either, as they were able to hold Hanie and the Chicago passing attack to less then 100 yards for the day.
If Kansas City is going to win any more games this season, they will need the defense to continue to play like they have in their last two games.
After watching Chiefs' RB Thomas Jones play against the Bears on Sunday, it's clear that this will likely be his last season in the league.
He had 16 carries in the game, and only mounted 36 rushing yards for his efforts.
That's an average of 2.3 YPC, which is hardly a decent average for any NFL running back.
Jones just doesn't have it anymore, and this season will likely be his last in the league.
I realize that Chiefs' starting QB Tyler Palko had a mistake-free day and led his team to victory on Sunday.
However, that is not the issue going forward.
Not only does Kansas City have a quarterback that cannot throw the ball more than 15 yards down the field, now they might not even have backup Kyle Orton for awhile.
With Orton's finger injury in the first half of this game and Palko's limited ability to throw the ball down the field, it will be very hard for the Chiefs to score points for the rest of the season.
Rookie outside linebacker Justin Houston had the best game of his young career on Sunday.
He harassed Bears' QB Caleb Hanie all game, and sacked him three times in the contest.
This is something that the Chiefs have been waiting to see from Houston for the entire season.
It looks like the KC defense might already have their pass-rushing threat opposite Tamba Hali for years to come.
Chiefs' coach Todd Haley picked up a big win for not only his team, but his job security against the Bears on Sunday.
Going into the game, Haley's team had lost four straight games and it looked like they wouldn't win another one this season.
Of course, that all changed on Sunday with a 10-3 win over the Bears.
Even though the offense still needs a lot of work, Haley can at least feel a little more comfortable to have his job this week.
