The Pittsburgh Steelers forced four turnovers in defeating the Tennessee Titans 19-13 Sunday at Heinz Field. Ryan Tannehill had a day to forget for Tennessee as he threw an interception and lost a fumble. It was one of three fumbles lost by the Titans. Despite a strong defensive performance, Tennessee fell to 9-and-5. It’s a short week for the Titans who host San Francisco Thursday night at Nissan Stadium.
