T.J. Watt set the Pittsburgh Steelers' franchise record for sacks in a single season during Sunday's 19-13 win over the Tennessee Titans.

James Harrison previously set the franchise record.

"T.J., congratulations on breaking my record and becoming the Steelers' new single-season sack-record holder," Harrison said in a video posted to social media. "But why stop there? Go on ahead and chase down that NFL single-season sack record and become the new holder of that, too."

Watt leads the NFL with 17 sacks this season. With 66.5 career sacks, Watt has the third-most sacks by a player in his first five seasons since 1982. Only Reggie White (81) and Watt's older brother, J.J. Watt (74.5), have more.
