Roethlisberger hurt in OT as Steelers fall to Chiefs Pittsburgh 24, Kansas City 27 When the last player drafted in 2009 trotted onto the field, the best team of 2008 was doomed. A few minutes after Ben Roethlisberger wobbled off the field Sunday with a possible concussion, Ryan Succop kicked a 22-yard field goal with 8:28 left in overtime and the Kansas City Chiefs snapped a team-record 10-game home losing streak with a 27-24 victory over the stunned Pittsburgh Steelers. Chris Chambers' 61-yard catch-and-run set up Succop, and "Mr. Irrelevant" booted through the game-winner for the Chiefs (3-7), whose stadium was crammed with tens of thousands of towel-waving fans of the Steelers (6-4). Roethlisberger had thrown for 398 yards and three touchdowns when he apparently took a knee to the helmet while being sacked by Derrick Johnson and gave way to Charlie Batch. Coach Mike Tomlin said he was not certain how severe the injury might be. Matt Cassel had a horrendous first half, passing for only 35 yards on four completions. But he came through in the final two quarters and overtime, finishing with 248 yards and two touchdowns. "I've got to hand it to [Cassel], the kid's a fighter," said Haley, who grew up accompanying his father to Steelers training camp, where the elder Haley worked as a personnel executive. Haley lost to Pittsburgh in last year's Super Bowl when he was Arizona's offensive coordinator.
