PHILADELPHIA - Nick Foles looked sharp, Michael Vick was nearly flawless, and the Eagles' quarterback competition remains close.

Foles and Vick each led the Eagles to touchdown drives in a 14-9 victory over Cam Newton and the Panthers on Thursday night.

No matter whom Chip Kelly chooses to run his up-tempo offense, it appears both quarterbacks can operate this system efficiently. Vick and Foles have combined to put up 28 points on eight-plus drives in two games.

Vick, the four-time Pro Bowl pick, has the statistical edge over Foles, a former Arizona Wildcat in his second year in the NFL. But Kelly hasn't given any indication he's leaning toward one over the other, and he seems willing to wait until after the preseason to pick a No. 1 guy.

Vick completed his first nine passes before throwing an interception on a Hail Mary at the end of the second quarter after the Eagles (1-1) got the ball with 24 seconds left in the half. He finished 9 of 10 for 105 yards and also ran for 20.

Foles was 6 of 8 for 53 yards. He had 13 yards rushing, including a 7-yard TD scamper. But Foles made a big mistake on his first series when he tried to throw the ball out of the end zone, and it was intercepted.

Through two games, Vick is 13 of 15 for 199 yards, one TD, one interception and a passer rating of 113.1. Foles is 11 of 14 for 96 yards, no TDs, one pick and a passer rating of 65.7.

Rookie Matt Barkley started the second half for the Eagles and went 8 of 14 for 72 yards.

• Bears 33, Chargers 28: In Chicago, Jay Cutler looked shaky again, but the defense made up for it, harassing Philip Rivers early on and setting the tone for the Bears.

All eyes remain on the quarterback after the Bears made some big changes on offense in the offseason, hiring coach Marc Trestman to replace Lovie Smith and revising their line.

So far, the results are mixed at best. Cutler played a quarter and completed 4 of 5 passes for 38 yards and a touchdown, but the only receiver he targeted was Brandon Marshall.

• Ravens 27, Falcons 23: In Baltimore, Matt Ryan threw for 97 yards and a touchdown in four series, and Atlanta limited Baltimore's starting offense to three first downs in the first half before the Ravens' backups rallied.

Under Ryan's direction, the Falcons starters pierced Baltimore for 11 first downs in 16 1/2 minutes and built a 20-7 lead at halftime.

It was 23-7 before Baltimore scored 20 fourth-quarter points, including a 78-yard punt return by Asa Jackson with 6:18 remaining.

• Browns 24, Lions 6: In Cleveland, Brandon Weeden threw two touchdown passes to Jordan Cameron and perhaps ended any more discussion about a quarterback competition in Cleveland.

Weeden connected on TD passes of 10 and 5 yards to Cameron in the first half as the Browns opened a 17-0 lead. Weeden finished 8 of 12 for 117 yards. In two weeks, he's 18 of 25 for 229 yards and three TDs.

Browns running back Trent Richardson made his 2013 exhibition debut and gained 33 yards on six carries, showing some elusiveness and power.

Extra points

• Patriots quarterback Tom Brady participated fully in the team's walkthrough Thursday, a day after he left practice with an apparent left knee injury. He jogged with other players at the start. He dropped back normally to throw passes. And he didn't limp.

The team did not say if he will play in tonight's exhibition against the Buccaneers.

• A day after moving atop Pittsburgh's depth chart at running back, Steelers rookie Le'Veon Bell's status is in doubt for Monday night's preseason game against the Redskins.

Bell aggravated a left knee injury during practice Thursday. Pittsburgh's second-round pick out of Michigan State was on the ground for several minutes while being attended to by trainers.

• Saints linebacker Jonathan Vilma has traveled to Philadelphia to have arthroscopic knee surgery, and how long he'll be sidelined remains unclear.

• Lions wide receiver Calvin Johnson did not play in Thursday's exhibition against the Browns because of a bruised knee.

• Jets quarterback Mark Sanchez will start over rookie Geno Smith, who was hobbled a bit this week with a sprained ankle, in the preseason home game against the Jaguars on Saturday night.

• Cowboys guard Ron Leary was sent home for more examinations on a right knee that probably needs surgery.

Coach Jason Garrett said Thursday the team didn't consider the injury serious and hoped to have Leary back at practice in "a couple of weeks."

• Bears defensive end Julius Peppers sat out his second straight preseason game Thursday night because of a hamstring injury.

• Browns rookie linebacker Barkevious Mingo was hospitalized with a bruised lung suffered during Cleveland's 24-6 victory over Detroit on Thursday.

• Colts safety LaRon Landry is likely to sit out Sunday's game against the Giants because of a knee injury.

• Browns running back Montario Hardesty underwent arthroscopic knee surgery and will likely miss at least the first two regular-season games.
