SAN DIEGO -- Fourth-and-29 at their own 37, 1:37 left in regulation and trailing by three points.
Six plays later, Justin Tucker kicked a 38-yard field goal to tie the game at 13 as regulation expired. Tucker made another 38-yarder with 1:07 left in overtime to win it.
But it was Rice's 29-yard gain that saved the day and allowed the Ravens (9-2) to take an even firmer grip on the AFC North race.
They got it.
The ball originally was spotted at the 33. After a lengthy review, the ball was moved back to the 34 and the refs measured. The new spot still gave the Ravens a first down by the length of the ball.
"It was just total will," Rice said. "Once I made the first guy miss when I cut back across the grain, I actually saw the defense had to flip their hip and I kept eyeing the first down. I looked and said, 'Should I keep running to the sideline or should I just keep trying to get up field?' And that's what I did. I just kept getting up field.
"I left it in the hands of the officials and I'm not going to say they owed us one, but I'm glad we came out on top," he said.
Said wide receiver Torrey Smith: "I had a great view. ... That's probably one of the best plays I've ever seen. You won't see too many plays like that. He was the perfect guy for it."
"I thought it might be our best shot at the time -- give it to Ray -- and Ray made a great run and got a little lucky and it worked out perfect," Flacco said.
All the Chargers had to do was get the stop and run out the clock for their first win against a team with a winning record this season.
"I don't know what to say," Jammer said. "A play like that should never happen. You can't give them a chance to execute that play. But we had some breakdowns, for sure."
Up to that point, San Diego's defense had played well.
"It definitely upsets the stomach when things like that happen, but they happen," said defensive end Corey Liuget, who had a sack, a big fourth-down stop earlier in the game and a pass deflection.
"You have to give a guy credit when he makes an awesome play like that. But it was big, the biggest of the game it changed the game. ... Those kinds of plays are never acceptable in the NFL. You have to have somebody make the play."
San Diego (4-7) was pushed closer to elimination from the playoff picture for the third straight season, and with it, almost certainly the end of the Norv Turner era. The Chargers dropped four games behind AFC West leader Denver, which swept the season series against San Diego. In the wild-card race, the Chargers trail Indianapolis by three games and Pittsburgh and Cincinnati by two games.
Baltimore increased its lead to three games over Pittsburgh, which lost to Cleveland, and Cincinnati, which beat Oakland. The Ravens won their fourth straight and for the eighth time in nine games.
This was the third time the Chargers blew a lead of double digits in the second half. They also came from ahead to lose at New Orleans and in an epic Monday night game here against Denver, when they blew a 24-0 halftime lead and lost 35-24.
NOTES: Chargers S Eric Weddle sustained a concussion when he was hit by Anquan Boldin on the fourth-and-29 play. Chargers S Atari Bigby and LB Donald Butler both left with groin injuries in the second quarter. ... Ravens TE Ed Dickson sprained a knee. ... The Ravens were 8 of 13 on third-down conversions in the second half and overtime, and 12 of 24 for the game. The Chargers were 3 of 15 on third-down conversions for the game.
