Not the one briefly issued to Manning at the 2004 NFL draft, of course. Just another victory against him.
"If you said we were going to be one game out of a playoff berth with three games to play, it wouldn't be ideal but I think we would sign up for that," said Rivers, who led the Chargers to just their second win in the last six games.
Manning was booed all day by fans who still remember the sleight they felt when Archie Manning, in the days before that draft, asked the Chargers not to take his son.
"That's not what the goal was," Manning said. "This organization and this team expects to make the playoffs and be in contention for championships and obviously to know that with three games to go, it's disappointing. Today's loss was a tough one."
Said Allen: "I think we got on top of these guys pretty early and put them out their misery. They didn't really want to play anymore."
Manning was picked off twice, the first time when Donald Butler came up with a deflected pass midway through the first quarter. Three plays later, Allen got open for a 43-yard play that he completed by lunging for the pylon for the score.
Allen had three catches to push his season total to 61, breaking LaDainian Tomlinson's team rookie record of 59 in 2001.
Rivers was 21-of-28 passing for 249 yards before being replaced by Charlie Whitehurst with more than five minutes left.
Manning was 20-of-32 passing for 259 yards, with one TD.
New York lost for just the second time in seven games following an 0-6 start.
Allen was hurt while making a 12-yard catch late in the first quarter and went into the locker room. He returned late in the second quarter and caught his second scoring pass to give San Diego a 17-0 lead.
Allen said he had an X-ray on his shoulder, which was negative, and then got a pain-killing shot before going back into the game.
"My shoulder's fine," he said. "I just fell too hard, just trying to dive and get away from the contact but I ended up hurting myself."
Rivers appeared to injure his neck when he dove for the loose ball but stayed in the game.
Manning threw a 5-yard touchdown pass to Brandon Myers, and Novak added field goals of 27 and 43 yards, all in the fourth quarter.
