Question: Passage: In a game that various analysts considered a potential Super Bowl XLVII preview, the 7-1 Bears faced the also 7-1 Houston Texans on Sunday Night Football, in a game waged in the rain. The first half proved disastrous for Chicago, as Kellen Davis had the ball stripped by former Bear Danieal Manning, and recovered by Texans linebacker Tim Dobbins. Shayne Graham later kicked a 20-yard field goal to give Houston the first points of the game. On Chicago's next possession, Michael Bush fumbled, and the Texans recovered again. The Texans drive wouldn't last long, as Tim Jennings would intercept Matt Schaub. However, the Bears failed to take advantage of the turnover, as Jay Cutler's pass would get intercepted by Manning. A quarter later, Jennings once again intercepted Schaub, which set up a Robbie Gould 51-yard field goal. Later in the quarter, Justin Forsett broke a 25-yard run to the Bears 3-yard line, which set up Arian Foster's 2-yard touchdown catch. Late in the first half, Cutler was hit by Dobbins, giving him a concussion, which sidelined him for the rest of the game, and was replaced by Jason Campbell. With less than two minutes left in the third quarter, Gould hit a 24-yard field goal to draw the Bears within four points, but Graham would make a 42-yarder to increase the deficit to seven with less than five minutes left in the game. Gould had attempted a 48-yard field goal earlier in the fourth quarter, but the ball hit the left upright. The loss snapped Chicago's six-game winning streak, the longest since their seven-game streak in 2006, and dropped Chicago to a 7-2 record, and 0-3 all-time against the Texans. 
Question: How many yards was the longest field goal of the game? 
Answer type: Number 

Answer: 51.
