Coming off their upset win over the New Orleans Saints, the Redskins continued their road trip and traveled to the Edward Jones Dome to meet the St. Louis Rams for a 5th consecutive season, and for the third consecutive season in St. Louis. The Redskins started the game very well with Josh Wilson recovering a Danny Amendola fumble and returning it to the endzone for a 7-0 Redskins lead on the first snap of the game. St. Louis would fight back, however, and pick up a Greg Zuerlein 39-yard field goal to cut the Redskins advantage to 7-3. Washington would close the first quarter with a Robert Griffin III touchdown run to give the Redskins a 14-3 lead going into the second quarter. In the second, St. Louis continued to battle, as Zuerlein hit another field goal. However, on the Redskins' ensuing possession, Griffin III connected with Leonard Hankerson for a 68-yard strike on a play action pass, and the Redskins appeared to take firm control, with a 21-6 edge. However, St. Louis would prove resilient, led by Danny Amendola's 12 receptions in the first half, St. Louis pulled within 8 when Sam Bradford found the aforementioned Amendola to cut the Redskins' advantage to 21-13. Then, just before the half, Griffin threw his first career interception to Cortland Finnegan which set up Zuerlein's 42-yard field goal as the half ended to cut the lead to 21-16. In the third, momentum continued to swing St. Louis' way as Bradford found a wide open Brandon Gibson to give St. Louis its first advantage of the game. Griffin III continued to amaze as he found the endzone for a second time on the ground, and Washington ended the third quarter up 28-23. However, late in the third, for the second straight week, a Saverio Rocca punt was blocked, this time by St. Louis tight end Matthew Mulligan. To open the fourth, Bradford found Mulligan, and rookie Daryl Richardson scampered into the endzone for the two-point conversion, and St. Louis led 31-28. Washington was unable to get into position to tie the game, but had an opportunity late when Richardson fumbled and DeJon Gomes picked it up to give Washington the ball with less than three minutes to play. Washington drove the ball to the St. Louis 29, which would have set up a 46-yard field goal attempt by Billy Cundiff, but Josh Morgan was flagged for unsportsmanlike conduct after he threw the ball at Cortland Finnegan, moving Washington back to the St. Louis 46, and making it a 62-yard field goal. Cundiff's attempt was wide right and well short of the distance, and St. Louis held on for the 31-28 win. With the loss, the Redskins fell to 1-1. Also, Washington fell to 2-3 in their last five games against St. Louis, dating back the 2008 NFL season. In that time, the Rams have compiled a 13-53 overall record.
