Write a question about the following article: In a game filled with snow similar to the Snowplow Game, the Dolphins would upset the Steelers 34-28 to keep their playoff hopes alive. The game is notable for the final play, in which the Steelers lateralled the ball 7 times, with the final lateral pass being caught by Antonio Brown in stride. Brown then sprinted down the sidelines, avoided several tackles, and sprinted into the endzone for an apparent game-winning touchdown. However, most noticeable on replay, Brown barely stepped out of bounds, with the left half of his foot barely touching the sideline. With the win, the Dolphins improved to 7-6.
What happened after Antonio Brown caught a lateral pass and sprinted down the sideline?
