The Raiders traveled to take on Washington on Sunday Night Football. Beginning a rough night for Derek Carr, on the second play of the game, Carr threw his first interception on the season. Washington took advantage of the turnover, driving 67 yards on eight plays as Kirk Cousins hit Chris Thompson on a 22-yard pass to give Washington the lead 7-0. The teams exchanged punts on each of their next three possessions, but the Raiders turned the ball over again with 10 minutes remaining in the second quarter when Carr was picked off for the second time in the game. Washington again took advantage, driving 72 yards and scoring their second touchdown on a Vernon Davis 18-yard touchdown catch. As a result, the Raiders trailed 14-0 at the half. The Raider offense was completely shut down in the first half, managing only 47 yards from scrimmage. Washington continued to dominate the Raiders in the second half, driving 75 yards on the opening possession and upping the lead to 21-0 on a Josh Doctson 52-yard touchdown catch. A punt by the Raiders followed and Washington missed a field goal attempt on their next possession as the score remained 21-0. On the Raiders next possession, they were forced to punt, but Jamison Crowder muffed the punt and the Raiders recovered at the Washington 18-yard line. Two plays later, Carr hit Jared Cook from 21 yards out to notch the Raiders first points and cutting the lead to 21-7. A Washington field goal moved the lead to 24-7 as the Raiders were forced to punt again. Following a fumble on the next Washington possession, the Raiders could not get into the end zone from the Washington 20 and were forced to settle for a Giorgio Tavecchio 22-yard field goal. Washington answered the field goal with their own to move the lead back to 17 at 27-10. Neither team could muster anything further as the Raiders fell 27-10. The loss moved the Raiders to 2-1 on the season. The disappointing performance was led by the Raider offense which went 0-11 on third down tries and managed only 128 total yards. Meanwhile, the Raider defense gave up 472 yards to Washington, 356 through the air.
