Coming off their win over the Browns, Washington traveled to Lincoln Financial Field for a rematch with the rival Philadelphia Eagles, who they beat 31-6 in Week 11. In the first, Philadelphia got the ball first, and subsequently got on the board first, as well, taking the opening kickoff and going on a drive in which they converted two fourth downs, and ended with quarterback Nick Foles finding wide receiver Jeremy Maclin for a 27-yard score and a 7-0 lead. Washington would be unable to answer in the quarter. In the second, Washington had good field position, as Richard Crawford had just recovered a Foles fumble and Washington converted the fumble into a Kai Forbath 45-yard field goal to cut the deficit to 7-3. Forbath's field goal was his 16th consecutive field goal to start his career, tying an NFL record. Following a Philadelphia punt, Washington drove and called on Forbath again, this time from 42 yards, and he delivered to cut the lead to 7-6. This field goal was his 17th consecutive make, setting an NFL mark for consecutive field goals made to start a career. On Philadelphia's ensuing possession, Foles was intercepted by London Fletcher, and Washington got the ball at the Eagles' 25. Washington turned Philadelphia's second turnover of the quarter into a Josh Morgan 13-yard touchdown pass from Robert Griffin III, back in after missing last week's game, for a 13-7 lead. Philadelphia would answer with an Alex Henery 38-yard field goal to cut the Washington lead to 13-10 at the half. In the third, Washington got the ball first, and drove down the field, capping off the drive with a 10-yard touchdown run by Alfred Morris to extend its advantage to 20-10. Philadelphia would respond with Henery connecting again, this time from 30 yards out, to cut the lead to 20-13. After exchanging punts, Washington got the ball back again, and this time Griffin found Santana Moss in the corner of the endzone for a 22-yard score and a 27-13 advantage. After a Philadelphia punt, Washington tried to drive down the field in an attempt to put the game on ice, but Griffin's pass was overthrown and intercepted by Colt Anderson of Philadelphia, and Philadelphia converted that into a Dion Lewis 17-yard scamper to cut Washington's advantage to 27-20. After Washington could not extend its advantage, Philadelphia got the ball back, and got into the red zone in the game's final minute. Despite an open Maclin in the endzone, Foles short-hopped the pass, and then tight end Evan Moore dropped another, and the Eagles had one final play. With 8 seconds remaining, Foles was pressured, threw an incomplete pass that did not reach the line of scrimmage, resulting in an illegal forward pass, and with only 1 second on the clock, the 1 second was run off due to the ten-second runoff rule, and Washington barely hung on for a 27-20 win. With the nail-biting win, Washington improved to 9-6, 4-1 in the NFC East, winning six straight for the first time since 1996, clinching a winning record against the NFC East for the first time since 2005 and a winning overall record for the first time since 2007. Additionally, the win guaranteed that they would be in control of their own destiny in their season finale against the Dallas Cowboys.  This is also the team's first seasonal sweep over the Eagles since 2008.. How many yards was the difference between the first and second field goals?
