CLEVELAND -- The Pittsburgh Steelers gave the Browns the lead with three fumbles in the first half, but the Browns gave it right back on a questionable touchdown right before halftime.
What made the score controversial was Rainey getting stuffed on a run up the middle by Browns linebackers Kaluka Maiava and D'Qwell Jackson. But the officials didn't blow the whistle, and Rainey bounced to the left side where he scored easily.
The Browns were upset because they thought Rainey's forward progress was stopped. But forward progress is not reviewable, so it couldn't be overturned by replay.
