CHICAGO — Woof.

Nick Foles and the rest of the NFL’s lovable underdogs, who used doubt to fuel them to their first Super Bowl title last season, are at it again. Foles conjured up some more of his playoff magic, connecting with Golden Tate for the go-ahead, 2-yard touchdown with 56 seconds left Sunday to lift Philadelphia over the Chicago Bears.

The two-point conversion failed, but Cody Parkey missed a 43-yard field goal with 10 seconds left, allowing the Eagles to escape with a 16-15 win in the NFC wild-card round. The kick by Parkey, who has been inconsistent all season, hit the left upright and then bounced off the crossbar for good measure. He was booed loudly as he left the field.

"He makes that 99 times out of 100," Foles said. "We're just fortunate that was the one he missed."

Philadelphia will play top-seeded New Orleans in next weekend’s division round. The Saints routed Philadelphia 48-7 in Week 11, a game that also was at the Superdome. But the Eagles have won six of seven since then, and anyone who doubts Foles and Philadelphia in the postseason does so at their own risk.

Foles, a career castoff, came in for Philadelphia after Carson Wentz blew out his knee last season and led the Eagles to a Super Bowl win over the New England Patriots. He’s started the last four games after Wentz suffered a back injury and, you guessed, it Philadelphia is 4-0 since then.

Three things we learned:

1. Coming up clutch

Given some of their best field position of the day when Pat O’Donnell shanked a punt, Foles drove the Eagles 60 yards and ate up a ton of the clock in the process.

The mighty Bears defense appeared to have stalled them inside the 15, when Wendell Smallwood ran smack into Akiem Hicks and could only pick up a yard. Foles’ pass intended for Nelson Angholor was incomplete, bringing up third-and-9 from the 13.

But have we told you about #FolesMagic? He connected with former Bear Alshon Jeffery for the 11-yard pickup. After no gains on the next three plays, he found Tate in the end zone.

2. Penalties will kill you in the playoffs

In case the Seattle Seahawks didn’t make that clear enough, the Bears and Eagles were there with the reminder.

Each of Chicago’s first two scoring drives included a flag on third down. They were dumb penalties, too, unnecessary roughness by Michael Bennett and hands to the face by Nigel Bradham.

But the Bears’ bad behavior was actually more costly. On Philadelphia’s touchdown drive in the third quarter, 52 of the 83 yards were courtesy of penalties. That included a 33-yard pass interference call on Prince Amukamara for manhandling Zach Ertz at the 10-yard line.

On the next play, Foles found his other tight end, Dallas Goedert, for the 10-yard score to give Philadelphia a 10-6 lead.

3. Where's Eddie?

Safety Eddie Jackson was active for the game but didn’t play.

Jackson, who had six interceptions during the regular season, missed the last two games with a sprained ankle. He was hurt after picking off Aaron Rodgers at the end of the Packers-Bears game last month.
