Mason Rudolph guided a long first-half touchdown drive to perhaps nudge ahead of Josh Dobbs in the race to be the backup behind Ben Roethlisberger and the Pittsburgh Steelers beat the Kansas City Chiefs 17-7.

Rudolph finished 10 of 15 for 77 yards while Dobbs completed 6 of 11 for 95 yards with a red-zone interception.

Kansas City star Patrick Mahomes played just two series for the Chiefs, completing 2 of 5 passes for 11 yards.
