Context: The Browns dropped their 13th consecutive season-opening game with a 21-18 loss to the Steelers. The scoring began early in the first quarter when Pittsburgh's Tyler Matakevich blocked a Britton Colquitt punt, knocking the ball into the end zone where it was recovered by Anthony Chickillo for a touchdown. The Browns were able to tie the score by the end of the first quarter, however, as rookie quarterback DeShone Kizer orchestrated a 12-play drive that ended when he scored on a 1-yard touchdown run. The game stayed at 7-7 through most of the second quarter, until the Steelers quarterback Ben Roethlisberger connected with tight end Jesse James on a 4-yard touchdown with 45 seconds left in the first half. The 7-play, 91-yard scoring drive was highlighted by a 50-yard reception by Antonio Brown on a tipped ball. After a Zane Gonzalez field goal brought the Browns within 14-10 early in the third quarter, the Steelers drove down the field again. Roethlisberger threw a second touchdown pass to James to put them up by 11, 21-10. The drive was boosted by a 41-yard pass interference penalty on Browns cornerback Jamar Taylor on a deep pass intended for Brown. The score remained 21-10 until under four minutes remained in the game, when Kizer was able to throw his first career touchdown pass to Corey Coleman. A two-point conversion run by Isaiah Crowell brought the Browns to within a field goal, 21-18. The Browns did not get a chance to score again, however, as the Steelers were able to run out the clock after a long pass from Roethlisberger to Brown. Browns head coach Hue Jackson challenged the ruling; however, the catch call on the field was upheld. The 13th-straight season-opening loss extended an NFL record for the Browns, who also fell to 1-18 in season openers since returning to the league in 1999.  The team also lost their 12th straight game against a divisional opponent.  The team started 0-1.
