PASS DEFENSE STANDS TALL AGAIN: Through 15 games of the 2014 season, the Chiefs defense continues to not have allowed an individual 300-yard passer nor a pass completion of 50 or more yards. Pittsburgh QB Ben Roethlisberger was 18 of 25 passes for 220 yards with a long of 44-yards to WR Martavis Bryant in today's contest.

HOUSTON CONTINUES DOMINANCE: LB Justin Houston recorded a six-yard sack of Pittsburgh QB Ben Roethlisberger to give him 18.0 sacks (-77.0 yards) on the season. His 18.0 sacks rank first in the NFL in 2014.

His 18.0 sacks in 2014 are the second-best single-season mark in franchise history, behind LB Derrick Thomas' mark of 20.0 sacks in 1990.

Houston now owns 44.5 sacks (-248.5 yards) for his career. His 44.5 sacks rank him tied for seventh in franchise history for most sacks. He became just the ninth player in franchise history to record 40.0 or more sacks.
