Browns rookie quarterback DeShone Kizer threw his first touchdown pass of his National Football League career with about four minutes left in the game. It was the first time the Steelers blocked a punt for a touchdown since 1998 against the Kansas City Chiefs.
Anthony Chickillo recovered a blocked punt in the end zone to give Pittsburgh an early 7-0 lead in the first quarter.

The Steelers made life miserable for the Browns quarterback - this time Kizer. He started 6-7 passing, and scored his first career TD on a one-yard run.
Brown caught 11 passes for 182 yards and drew a 41-yard pass interference penalty that set up a 2-yard touchdown pass to James that gave the Steelers a 21-10 lead in the third quarter. That's when Watt came up with a huge play, intercepting Kizer and returning it 17 yards.
James Conner said Thursday that while he and Bell split reps evenly in practice, he expects Bell will start and get most of the carries in Sunday's 1 p.m. kickoff at FirstEnergy Stadium. He just missed picking off a pass in the second quarter.
The half ended with Joe Haden, recently cut by the Browns after seven seasons before signing with the Steelers, sacking Kizer.
It wasn't an ideal start for the Browns season, but it was hardly Kizer's fault. QB Kevin Hogan, with zero National Football League starts, backed up rookie DeShone Kizer.
