Answer based on context:

Coming off their disappointing loss to the Jets, the Steelers went home for a Week 12 Monday Night intraconference duel with the winless Miami Dolphins. Playing in heavy rain with a delay due to lightning, the game remained scoreless through 59&#160;minutes and 43&#160;seconds, becoming the longest scoreless tie since November 7, 1943. In the end, Pittsburgh came through with kicker Jeff Reed nailing the game-winning 24-yard field goal with 17&#160;seconds left for the game's lone points. With the win, the Steelers improved to 8-3.  Also, not only did they improve their home record to 6-0, but this also marked their 13th-straight home win on Monday Night Football.  This game would also be crowned as the lowest-scoring game in Monday Night Football history. It was the lowest scoring NFL game since December 11, 1993, when the New York Jets defeated Washington by the same score.

How long was the winning field goal?
24-yard
