Task: Question Answering
Input (English): Passage: Trying to end a seven-game skid, the Raiders played their final home game of the season against the Kansas City Chiefs in an AFC West rematch on Saturday night.  In the first quarter, Oakland struck first with kicker Sebastian Janikowski getting a 25-yard field goal.  However, the Chiefs responded with QB Trent Green's 6-yard TD pass to WR Eddie Kennison, along with kicker Lawrence Tynes' 29-yard field goal.  In the second quarter, the Raiders responded with Janikowski's 37-yard field goal.  Unfortunately, K.C. RB Larry Johnson got a 1-yard TD run.  In the third quarter, Oakland managed to get the only score of the period with Janikowski's 53-yard field goal.  However, the Chiefs wrapped the game up in the fourth quarter with Tynes' 28-yard field goal.  With their eighth-straight loss, the Raiders fell to 2-13.  Also with the loss, they lost 13 games for the first time since 1961 and it even marked the first time in Raiders history that they lost eight consecutive games to one team (the Chiefs). Some of causes to Oakland's loss came from five turnovers (two interceptions and three lost fumbles), continuous penalty problems (6 penalties for 45 yards), and a year-long lack of offense. 
Question: How many yards was Janikowski's longest field goal? 
Answer type: Number 
Output (English): 53.
