Input (English): Passage: Coming off their bye week, the Raiders went home, donned their throwbacks, and played a Week 10 AFL Legacy game with the Kansas City Chiefs.  In the first quarter, Oakland struck first with a 1-yard touchdown run from running back Justin Fargas.  The Chiefs would get on the boards via a 50-yard field goal from kicker Ryan Succop, yet the Raiders came right back with their own 50-yard field goal from kicker Sebastian Janikowski.  However, Kansas City would take the lead in the second quarter with running back Jamaal Charles getting a 44-yard touchdown run and Succop booting a 25-yard field goal.  After a scoreless third quarter, the Chiefs would pull away as Succop nailed a 31-yard field goal.
