Coming off their season-sweeping win over the Bengals, the Steelers stayed at home, donned their throwback uniforms again, and played a Week 14 AFC North duel with the Cleveland Browns on Thursday night.  Pittsburgh trailed early in the first quarter as Browns kicker Phil Dawson got a 20-yard field goal.  The Steelers would answer with quarterback Ben Roethlisberger finding wide receiver Jerricho Cotchery on an 11-yard touchdown pass.  After a scoreless second and third quarter (which saw Roethlisberger suffer a left high-ankle sprain near the end of the first half and yet returned for the start of the second), Pittsburgh pulled away in the fourth quarter with Roethlisberger hooking up with wide receiver Antonio Brown on a 79-yard touchdown pass.. How many yards was the shortest touchdown pass?
