MIAMI — Cam Newton lofted a long pass that fell incomplete on the final play of the first half Friday night, and that’s the closest he came to reaching the end zone.

The top pick of the NFL draft was shut out in his first exhibition-game start, and Newton’s Carolina Panthers lost to the Miami Dolphins 20-10.

Newton played the entire first half, when the Panthers managed only three first downs, had the ball for less than eight minutes and fell behind 17-0. Newton went 7 for 14 for 66 yards, and he ran four times for 18 yards.

Carolina crossed midfield for the first time when Newton ran for 7 yards on the next-to-last play of the half.

Packers 28, Cards 20

Aaron Rodgers topped off a sharp performance with a 20-yard touchdown pass to Greg Jennings for the defending Super Bowl champions.

Rodgers played into the second quarter, completing 9 of 12 passes for 97 yards and the touchdown. Matt Flynn took over for Rodgers and led the Packers to another touchdown before halftime, a 2-yard run by rookie Alex Green.

Cardinals quarterback Kevin Kolb was 6 for 11 for 80 yards for the Cardinals, who were called for nine penalties in the first half, including several sloppy mistakes on offense.

Richard Bartel threw a 7-yard touchdown pass to Stephen Williams and Alfonso Smith added a 1-yard touchdown run to give the Cardinals the lead in the third quarter.

Ravens 31, Chiefs 13

Backup quarterback Tyrod Taylor directed two fourth-quarter touchdown drives for Baltimore, the first ending with Jalen Parmele’s go-ahead 10-yard touchdown run with 7:16 remaining.

Taylor later added a 5-yard TD run of his own, a dive to the right pylon that withstood a video review. He finished 5 for 11 for 88 yards.

Kansas City’s Tyler Palko completed eight of 13 passes for 95 yards, but produced 10 points in his three drives — a tying 4-yard touchdown pass to Terrance Copper late in the second quarter and a 12-play march culminating in a tiebreaking 30-yard field goal by Ryan Succop with 6:58 left in the third quarter.

Jaguars 15, Falcons 13

David Garrard did little to solidify his starting spot and rookie Blaine Gabbert was equally unimpressive for the Jaguars.

Garrard completed 7 of 12 passes for 99 yards, with an interception in three series. Gabbert, the 10th pick in the April draft, completed 11 of 23 passes for 96 yards in seven series.

Redskins 16, Colts 3

One week after Rex Grossman’s impressive performance, John Beck answered by leading the Redskins to four straight scores in the first half.

Beck and Grossman are fighting to become Washington’s starting quarterback, and after two weeks, the race appears even.

Grossman was 19 of 26 for 207 yards in a 16-7 win over defending AFC champion Pittsburgh last week. Beck’s answer: 14 of 17 for 140 yards, no touchdowns and no interceptions against the defending AFC South champs. With Beck in the game, the Redskins outgained the Colts 277-41 in the first half, ran more than twice as many plays (41-14) and had two 50-plus yard runs.

Lions 30, Browns 28

Colt McCoy threw three touchdown passes — two to tight end Evan Moore — in the first half, but Cleveland blew a 15-point lead in a penalty-filled exhibition.

McCoy finished 10 of 18 for 96 yards, his second straight solid performance running first-year Browns coach Pat Shurmur’s new West Coast offense. McCoy was victimized by a few drops but didn’t force any throws while playing most of the first half.

The Lions trailed by 10 entering the fourth, but got a 20-yard TD pass from Drew Stanton and Dave Rayner’s 48-yard field goal.

The officiating crew had a busy night: The teams were assessed 26 penalties for 211 yards.

Moore caught TDs of 2 and 21 yards, rookie Greg Little grabbed a 13-yarder from McCoy, and rookie Armond Smith had an 81-yard TD run in the third for the Browns.
