"We can build on a game like this, but we have to find a way as a team to come up on the other side of this kind of game," Kansas City linebacker Tamba Hali said. "Instead of being in the 'L' column, we have to be in the 'W' column."

Tomlin said of squeaking out a win against a 13-point underdog, "We'll take it. Such is life in the NFL. The guys made the necessary plays, particularly Lawrence Timmons, there for us in overtime."

NOTES: Kansas City placed defensive end Glenn Dorsey on injured reserve before the game with a calf injury and added cornerback Neiko Thorpe to the active roster from the practice squad. Dorsey, the fifth overall selection in the 2008 draft, played in just four games this season and was in on seven tackles. ... The Chiefs made wide receiver Steve Breaston a healthy scratch. Despite playing in each of the first eight games, Breaston has just six catches for 61 yards. ... Pittsburgh released nose tackle Alameda Ta'amu, its fourth-round draft choice this year, before the game to clear a spot on the roster for wide receiver David Gilreath, who was activated from the practice squad. Ta'amu returned to the Steelers on Oct. 30 following a two-game suspension imposed by the team. He was arrested on Oct. 14 after allegedly leading police on a drunken chase by vehicle and on foot through the streets of Pittsburgh. Ta'amu was charged with felony fleeing police, aggravated assault and aggravated assault by vehicle. ... Steelers wide receiver Antonio Brown missed a game for the first time in his three-year career because of a sprained ankle. He was one of four inactive Pittsburgh starters, along with running back Rashard Mendenhall (Achilles), safety Troy Polamalu (calf) and offensive tackle Marcus Gilbert (ankle).
