With Charles gashing Pittsburgh’s defensive line and Cassel avoiding mistakes, Kansas City raced in front 10-0. Cassel hit Tony Moeaki for 38 yards on the Chiefs’ second drive, setting up a 12-yard touchdown run by Charles to give Kansas City its first lead since a 7-3 victory over Denver in the 2011 regular-season finale.
The lead grew to 10-0 after an Isaac Redman fumble deep in Pittsburgh territory led to a 22-yard field goal by Succop.
‘‘I think we played well in all phases,’’ Cassel said. ‘‘That was the first time we played well together this year.’’
Like any brief flirtation with success for Kansas City, it didn’t last. The Steelers pulled even at halftime on a 35-yard field goal by Suisham and a remarkable 7-yard touchdown grab in the corner of the end zone. The ball slid through Wallace’s hands, but he secured it with his legs — and controlled it — before rolling out of bounds.
There would be no second-half carryover, however. Whatever energy the Steelers had vanished the second Roethlisberger trudged to the sideline holding his right shoulder.
In that moment all the chatter about Kansas City’s visit and former Chiefs coach turned Pittsburgh offensive coordinator Todd Haley’s shot at revenge vanished.
NOTES: The Steelers have won 15 consecutive home games on Monday night ... Roethlisberger topped 1,000 career rushing yards with a 13-yard scramble in the first half ... Pittsburgh S Ryan Clark left the game in the fourth quarter with a concussion.
