Both linebacker James Harrison and quarterback Ben Roethlisberger suffered scares in the first quarter. Harrison hurt his hip diving for a tackle in the first quarter, while Roethlisberger was groggy after a big hit and fumble on a quarterback sneak.
Both players have since returned to the game, but it was a scary series of events for Pittsburgh nonetheless.
The Titans are leading, 10-7, in the second quarter.
