Fourth quarter:

Mike Shanahan made his second switch of the year at quarterback, and it didn’t matter. Rex Grossman threw two interceptions – the second the play of the game – and Washington lost its fifth straight game, a 20-9 decision to the Miami Dolphins. It’s the first five-game losing streak of Shanahan’s head-coaching career.

The Redskins opened the fourth quarter trailing 13-9, with the ball on the Miami 38, a chance to take the lead for the first time all day. After working the ball to the 32, Grossman hit rookie receiver Leonard Hankerson on third and 10 for 22 yards to give the Redskins a first down at the 10. Their first touchdown of the day would have given them the lead.

But on first down, Grossman dropped back. He looked for receiver Jabar Gaffney cutting across the middle, and threw into heavy traffic. There, Dolphins linebacker Karlos Dansby came up with a relatively easy interception – Grossman’s second of the day – and the Redskins’ drive was snuffed out.

The Dolphins turned that into the game-clinching drive, on which they converted a third-and-8 with a pass from Matt Moore to tight end Anthony Fasano. They capped the drive with an 18-yard touchdown run by Reggie Bush, the score that gave Miami a 20-9 lead with 6 minutes, 7 seconds remaining.

Grossman did lead Washington to the Miami 28, but defensive end Jason Taylor – a Redskin for one season, in 2008 – sacked Grossman. On fourth down, Graham Gano tried a 49-yard field goal that would have cut the deficit to eight points. But the kick was wide left, and with 2:51 remaining, the Dolphins needed only to grind out the clock.

Third quarter:

The Redskins and Dolphins exchanged field goals in the third quarter, and Miami carried a 13-9 lead into the final quarter of play.

Washington started the half strong. On Miami’s second play from scrimmage, linebacker Ryan Kerrigan sacked quarterback Matt Moore, springing the ball loose. Stephen Bowen recovered it, and Washington started its drive on the Dolphins’ 24-yard line.

Despite the fortunate starting field position, the Redskins again couldn’t find the end zone. The Redskins got as close as the 5-yard line. Fred Davis caught Rex Grossman’s third-down pass in the corner of the end zone but couldn’t get his feet in-bounds. Graham Gano’s 23-yard field goal cut the Miami lead to 10-9.

On the Dolphins’ ensuing drive, Moore moved the team 70 yards downfield and reached the Washington 10-yard line before the drive stalled. Dan Carpenter chipped in a 28-yard field goal to give the Dolphins the 13-9 advantage.

Grossman continues his efficient, workmanlike performance. He was 7 of 10 passing for 52 yards in the quarter. Torain didn’t get a single touch in the quarter, but Roy Helu came off the bench and had 14 yards on a pair of carries. Hankerson has continued to enjoy a good afternoon. Entering the final quarter, he already has 75 yards on six catches.

Second quarter:

The Redskins were able to move the football -- a little -- but had few points to show for it in the second quarter. The Redskins and Dolphins each added a field goal and Miami took a 10-6 lead into the half.

As the half wound down, QB Rex Grossman moved the Redskins toward the red zone, but the drive stalled and Washington had to settle for Graham Gano’s 47-yard field goal.

Before that, Washington’s best drive came midway through the quarter when Grossman led the Redskins into Miami territory. But the Dolphins sent heavy pressure on third-and-six from the Miami 41-yard line, and Grossman heaved up the ball. Receiver Leonard Hankerson slipped on his route and Vontae Davis came up with the interception.

The Dolphins missed a 49-yard field goal attempt on the ensuing possession, but Dan Carpenter was able to chip in a 21-yarder earlier in the quarter.

At the half, Grossman was 9-of-12 passing passing for 103 yards and an interception.

The Redskins tried to establish their running game early, but Ryan Torain had only 20 yards on 11 carries in the first half.

In just his second career start, Hankerson led the team with 38 yards on 3 receptions.

The Redskins defense held Miami to only 123 yards of total offense in the first half, but the Dolphins still held a slim advantage on the scoreboard heading into the third quarter.

First quarter:

Rex Grossman’s second stint of the season as starting quarterback for the Washington Redskins got off to a sluggish start as the Miami Dolphins took a 7-3 lead into the second quarter.

Washington won the toss but went three-and-out on its first possession. An 11-yard sack off the right edge brought on fourth down.

The Dolphins responded with an eight-play 45-yard scoring drive capped with a 1-yard Reggie Bush touchdown run. Bush took the handoff, hit the middle of the line, where he quickly met opposition, and then bounced it to the left and trotted into the end zone with not a single Redskins player coming off the edge.

Washington’s second offensive possession featured 17- and 20-yard completions by Grossman, and Washington reached the Miami 20-yard line. But on third down, Jared Ordick blew past rookie left guard Maurice Hurt and dropped Grossman for a 12-yard-loss. Graham Gano attempted a 50-yard field goal, but it missed, wide left.

Washington’s defense got the ball back shortly after, however. Kevin Barnes picked off a Matt Moore pass and returned it to the 5-yard line.

The Redskins managed only three points off the turnover.

Ryan Torain scampered in from a yard out on a stretch play, but tight end Logan Paulsen was flagged for holding, backing Washington up 10 yards. The Redskins got back to the 8-yard line and had to settle for a 26-yard field goal by Gano.
