Timmons dropped into a hook-to-curl zone and intercepted a Matt Cassel pass, setting up a Steelers field goal for the overtime win. They may have won the game, but they lost quarterback Ben Roethlisberger, who left the game with a right (throwing) shoulder injury in the third quarter.
Some things change, but some things still end with Kansas City turning the ball over.
The Chiefs, the most turnover-prone team in the league, protected the ball throughout regulation, but Cassel's pass in overtime to an unknown recipient saved the Steelers from dramatic upset.
Overcoming a ferocious defensive effort - much like they provided last year when Pittsburgh defeated the Chiefs 13-9. Outside linebackers Tamba Hali and Juston Houston abused Steelers' tackles Max Starks and Mike Adams, and when they weren't, the Chiefs brought pressure up the middle.
Pressure so bad, it knocked Steelers starting quarterback Ben Roethlisberger out of the game with what appeared to be a right (throwing) shoulder injury.
One player who didn't feel the pressure the Chiefs brought last year, quarterback Byron Leftwich, came into a war zone.
Leftwich entered the game for Roethlisberger in the third quarter after he was sacked by Houston - after pinballing off Hali. He was hit early, hard and often in his first appearance in nearly three years, but managed to lead the offense to one field goal in the second half - the only points scored in the game's final 30 minutes.
He was the perfect metaphor for the team on the night; slow, cold and plodding, but just effective enough to pull off the win. After what appeared to be a communication snafu on the sideline, the Steelers burned a timeout before Leftwich hit fullback Will Johnson on a short pass, and Jonathan Dwyer came within inches of what would have been a game-clinching first down.
Instead, the Steelers punted to the Chiefs, who proceeded to find a few seams in the Steelers' defense, converting a huge fourth down pass from Matt Cassel to Dwayne Bowe, setting up Ryan Succop's tying field goal at the end of regulation.
It was the Steelers' 15th straight home win on Monday Night Football, and had to be one of their worst performances, win or lose, during that stretch. The Steelers' defense tightened up down the stretch, but gave up big passes at the end, setting up the tying field goal.
Their fourth consecutive win is just that, but it came at the price of losing Roethlisberger for the remainder of this game, and possibly longer. Roethlisberger left the stadium, and will be evaluated as the week progresses. If it is a shoulder separation, as it appeared, it's highly unlikely he'll play against Baltimore in Week 11 - a game with massive playoff implications.
