A.J. Green was partly correct. The defending Super Bowl champions do have a lot of holes on the defense.

And everywhere else, it turns out.

Andy Dalton threw a career-high four touchdown passes -- each to a different receiver -- and the host Cincinnati Bengals ended their four-game losing streak by beating the reeling New York Giants 31-13 on Sunday.

The Bengals (4-5) took advantage of a championship team that appears to have hit bottom. Eli Manning threw two interceptions that led to third-quarter touchdowns, and New York (6-4) had four turnovers in the second half overall.

The talk heading into the game was generated by Green, who suggested to a New York radio station that the Giants "have a lot of holes" on their defense.

Couldn't argue that point after the Bengals rolled up 31 points in only three quarters. "I just feel like this is a good stepping block for us," said Green, who had the first of the four TDs. "I put a lot of pressure on myself."

Now, the Giants are starting to feel a little pressure themselves.

They head into their off week with back-to-back losses and a lot of issues, especially on offense.

"No, I'm not worried," Manning said. "Over the years, we've gone through stretches where we haven't played our best football and we've been able to bounce out of that, and that's what's going on right now."

Peterson just getting rolling: Adrian Peterson trampled the Detroit Lions down the stretch, then said again he's still not 100 percent healthy. With Christian Ponder and the rest of the Vikings providing the necessary balance this time, Peterson padded his NFL rushing lead and put that supposedly devastating knee injury even further in the past.

Peterson raced 61 yards for the game-sealing touchdown midway through the fourth quarter, finishing with 171 yards on 27 carries for the Vikings in a 34-24 victory over the Lions.

"I still can get stronger. I'm still not there, man. I'm pressing to get there," Peterson said, adding: "I'm going to come back stronger and better after the bye."

Fox's triumphant return: Moments after the Denver Broncos gave the Carolina Panthers a good old-fashioned shellacking, they gave coach John Fox a game ball.

"There were a lot of motivating factors to help us win this game, and Coach Fox was the biggest one," Von Miller said.

Peyton Manning made sure Fox's return to Carolina was successful, throwing for 301 yards and a touchdown, and the defense turned in a dominating performance to lead the Broncos to a 36-14 rout.

Manning threw his 420th touchdown pass to move into a tie for second place on the NFL's list with his childhood hero Dan Marino. He trails only Brett Favre (508).

Fox spent nine seasons in Carolina before his relationship with owner Jerry Richardson dramatically deteriorated when the organization failed to offer him a contract extension.

So Sunday's win was a taste of revenge, although Fox took the high road after the game.

"You just feel good to win," Fox said.

Foles makes Eagles debut: Rookie quarterback Nick Foles finally got his chance with Philadelphia when a woozy Michael Vick could not continue. It was the second quarter of a 38-23 loss to Dallas, another low note in what could amount to coach Andy Reid's farewell season with the Eagles.

After Vick left with a concussion, Foles, a former University of Arizona star, could not save the game. He helped the Eagles to a 17-10 third-quarter lead before the team unraveled in the fourth quarter, allowing two defensive touchdowns and a special teams touchdown.

"Not good enough to win," Foles said after completing 22 of 32 passes for 219 yards, one touchdown and one interception.

The Eagles' fifth consecutive loss dropped them to 3-6. It's the first time Reid has lost five straight games in his 14 years in Philadelphia.

"Right now, we are what we are," Reid said. "So we have to change that around, and I believe we have the players to do that."
