The 2011Kansas City Chiefsseason is the franchise's 42nd season in the National Football League, the 52nd overall and the third under the head coach/general manager tandem of Todd Haley and Scott Pioli. The Chiefs are coming off a 10–6 record in 2010, in which the team won its first AFC West division title since 2003. Their 2011 schedule, which in terms of opponent win percentage, is ranked 3rd (tied) in the NFL and will feature all four conference championship teams from the 2010 season, (Bears, Jets, Packers, and Steelers), all over four consecutive weeks. They are the only team in the league to play all four teams in the 2011 season.
On July 25, the NFLPA and the NFL owners agreed on a new collective bargaining agreement. The Chiefs training camp began on July 29 in St. Joseph, MO. The Chiefs played their first preseason game on August 12 against the Tampa Bay Buccaneers. On September 11, the Chiefs opened their regular season against the Buffalo Bills. Despite entering the season with high expectations, even with their tough schedule, they did not earn their first win until Week 4 against the Minnesota Vikings and finished the first quarter of the season with a disappointing 1-3 record. After starting the season 5-8, head coach Todd Haley was fired after a 37–10 loss the New York Jets and replaced by defensive coordinator Romeo Crennel on an interim basis for the remainder of the season.

Hoping to snap a three-game losing streak, the Chiefs went home for a Week 12 Sunday night duel with the Pittsburgh Steelers. Kansas City delivered the game's first punch in the opening quarter with a 41-yard field goal from kicker Ryan Succop. The Steelers would answer in the second quarter with kicker Shaun Suisham getting a 21-yard field goal, followed by quarterback Ben Roethlisberger completing a 2-yard touchdown pass to tight end Weslye Saunders. The Chiefs would reply with a 49-yard field goal from Succop, but Pittsburgh would close out the half with Suisham booting a 49-yard field goal. After a scoreless third quarter, Kansas City began to chip away at their deficit in the fourth quarter with a 40-yard field goal from Succop. However, the Steelers' defense held on to preserve the win.
