The Giants' defense was trashed by the media during Week 4, their bye week, as they had allowed a whopping 92 points in their first three games, roughly 31 per game. After forcing a punt, the Giants drove to the Washington 29, but Jay Feely was wide left on a 47-yard attempt. Aided by a William Joseph roughing-the-passer penalty on 3rd-and-11 that would have forced a Washington punt, Mark Brunell drove the Redskins to the Giants' 21, where John Hall nailed a 39-yard field goal. Manning was unfazed, finding Amani Toomer on a 44-yard completion to move the ball to the Washington 10, and apparently finding him for a touchdown pass of 5 yards three plays later, but the score was nullified by a Jeremy Shockey pass-interference penalty. Feely knocked in a chip shot of 24 yards to tie the score, 3-3, early in the second quarter. Manning would again use the big play to help the Giants to their next score, finding Plaxico Burress on a 46-yard completion that gave the Giants the ball at the Redskins' 22. Soon after, Feely hit a 34-yard field goal to give the Giants their first lead since Week 2. After forcing a punt, Manning led the Giants on a 14-play, 84-yard drive, capped by a 32-yard field goal by Feely, his third of the quarter and half. The Giants' offense finally ground into gear on the first possession of the second half, going on a 15-play, 69-yard drive that ate up 8:05 of the clock, capped by a 2-yard touchdown toss from Manning to Burress. The Redskins could muster only one scoring opportunity the rest of the way (Hall missed a 42-yard field goal wide left the possession after Burress' touchdown), and Feely added a 40-yard field goal with 2:58 to play, capping the scoring.
