LANDOVER, Md. (AP) - Robert Griffin III went head-first instead of sliding, so when the ball popped out it was a fumble.
Aldrick Robinson had a touchdown catch in his hands, but he couldn't quite maintain possession as he hit the ground in the end zone.
Thanks to the turf, the Detroit Lions have ended more than 70 years of road failure against the Washington Redskins.
Detroit’s Calvin Johnson escapes the grasp of Washington’s London Fletcher and rolls into the end zone for a touchdown during the second half Sunday.
Detroit beat Washington 27-20 Sunday with big days from Matthew Stafford, Calvin Johnson and Nate Burleson and those two fourth-quarter Redskins bobbles, the kinds of breaks that had eluded Detroit (2-1) in the nation's capital since Franklin Delano Roosevelt lived on Pennsylvania Avenue.
"You never know how the cookie's going to crumble, and it feels good that it crumbled our way this time," Detroit cornerback Rashean Mathis said.
"I wasn't a part of the past, but I am part of the future, so it feels good to give the fans something to feel good about, and we can demolish a record, our streak, that was going on for years and years and years."
Detroit's last road victory in the series came in 1935 against the Boston Redskins, two years before the move to Washington (0-3). That 21-game streak was the second-longest in NFL history.
History was at play in other ways. The "Calvin Johnson rule" - in which a receiver must maintain possession of the ball all the way to the ground when falling during a catch - worked in favor of the Lions for a change.
The rule was named after Johnson after he had a catch in the end zone overturned three years ago against the Chicago Bears.
This time it was Robinson who wasn't quite able to keep the ball from coming loose after hauling in a pass from Griffin for an apparent 57-yard touchdown. The score would have given the Redskins the lead with 9:05 to play, but it was overturned by replay.
"I'm not known for my calm or anything like that," Detroit coach Jim Schwartz said. "But if that hadn't got overruled, I would have had a difficult time. I might have had a conniption or whatever that is."
Then there was Griffin, who finally resembled the RG3 of last year when he scrambled to make something out of nothing with a 21-yard run deep into the opponent's territory with the score tied in the fourth quarter.
But the ball jarred loose as Griffin stumbled forward to give himself up at the 30-yard line. The play would have been ruled dead if he had slid, something he said he would do more often this year.
Because he was going head-first, it became a fumble recovered by the Lions.
"It's the rule. It can be a (bad) rule, but it's still one of the NFL rules, and they said it's a fumble," Griffin said. "So, it's unfortunate, and I've just got to make sure if I dive forward, hold onto the ball. ... It was really unfortunate that we lost the game on two calls, two judgment calls."
On the next play after Griffin's fumble, Johnson started a drive with a tiptoe catch along the sideline, and David Akers ended it with a 28-yard field goal with 11:08 to play to give the Lions the lead for good.
After Robinson's non-catch, Detroit got an insurance touchdown with 3:56 remaining on Stafford's 11-yard pass to Johnson, who had four Redskins around him as he fought his way across the goal line.
Johnson had 115 yards receiving, tying Herman Moore for the franchise record with 34 career 100-yard receiving games.
Nate Burleson had 116 yard receiving, and Stafford completed 25 of 42 passes for 385 yards against a defense ranked by far at the bottom of the NFL after two weeks.
Griffin completed 32 of 50 passes for 326 yards and had his fourth interception of the season, one shy of his total from all of 2012. He's the first player in Redskins history to throw for 300 yards in three straight games, a byproduct of spending most of his time this season playing catch-up.
Griffin said leading up to the game that he would run the ball more to give his team a spark, but he rushed only six times for 37 yards, including his first carry out of the zone read this season.
The Redskins also scored an offensive touchdown for the first time this season, but they're nevertheless 0-3 for the first time since 2001.
"The food isn't going to taste that good tonight," Washington cornerback DeAngelo Hall said. "Still trying to wrap my head around what we can do to get better."
Notes: Lions DT Jason Jones ruptured his left patella tendon in the second quarter and is out for the year, and RB Reggie Bush missed the game with a left knee injury.
