Defense steps up without Porter Jr. in 20-13 Week 1 win over Atlanta

Without Joey Porter Jr. in the lineup, Pittsburgh's defense still dominated Atlanta's backup quarterback, holding the Falcons to 13 points in a 20-13 Week 1 win.

Cameron Heyward was disruptive up front, helping fill the void left by Porter's absence and keeping Atlanta's offense in check throughout.

The Steelers are 1-0 and will look to get Porter back for their Week 2 road game on September 20.
