Baltimore Ravens quarterback Kyle Boller looks for a receiver during the first quarter of an NFL preseason game against New England.

FOXBOROUGH, Mass. (AP) — With Tom Brady having the night off, the Patriots were far from perfect in their first game after a nearly perfect season. For John Harbaugh, the Ravens' 16-15 exhibition win Thursday was a good start to his head coaching career.

Harbaugh got a look at the quarterbacks competing to succeed the retired Steve McNair. Kyle Boller started for Baltimore, Troy Smith replaced him and both played decently. First-round draft pick Joe Flacco looked like a rookie, losing a fumble on his second play.

Three quarterbacks are competing to be Brady's backup on a team that was 18-0 before losing the Super Bowl to the New York Giants.

Third-round choice Kevin O'Connell led the Patriots to their only touchdown on a 31-yard march after Flacco's fumble. But O'Connell played the last third of the game against defenders far down on the depth chart.

Another newcomer to New England had one of the best games for the team. LaMont Jordan, fighting for a job behind Laurence Maroney, ran with power, picking up 76 yards and scoring on a 1-yard run just 13 days after being released by Oakland following his seventh NFL season.

The Ravens got key plays from Yamon Figurs with a 52-yard punt return that set up their only touchdown and a 48-yard kickoff return that led to one of Matt Stover's two field goals.

JETS 24, BROWNS 20: At Cleveland, Brett Favre's big-play ability rubbed off on the New York Jets, who scored three long touchdowns in a 24-20 win over the Cleveland Browns as their new star quarterback watched from the sideline Thursday night.

Dwight Lowery returned a punt 62 yards to score with 10:02 left to cap New York's comeback from a 10-point deficit. Lowery and Hank Poteat both intercepted passes by Ken Dorsey in the final four minutes to preserve the lead.

The Browns got yet another chance in the final seconds after a roughing-the-passer penalty and pass interference call put the ball on the 5. Dorsey's ninth straight incompletion on the possession fell short as time expired.

SAINTS 24, CARDINALS 10: At Glendale, Ariz., Drew Brees and Matt Leinart started the preseason with near-perfection.

Brees was 6-for-7 for 40 yards and a touchdown in his lone series in the short-handed New Orleans Saints' 24-10 victory over the Arizona Cardinals on Thursday night. Saints backup Mark Brunell was equally effective, completing 10 of 12 for 119 yards.

Leinart, the third-year Arizona quarterback who missed the final 11 games last season due to a broken collarbone, completed eight of nine passes for 91 yards in the first two series of the game.

LIONS 13, GIANTS 10: At Detroit, Eli Manning and the Super Bowl champion New York Giants finally stumbled on the road.

Only this time, it didn't really matter.

Manning, the Super Bowl MVP, struggled on his only two series in the preseason opener, and the Giants lost to the Detroit Lions 13-10 on Thursday night. New York won its final 11 games away from Giants Stadium last season, including all four in the playoffs en route to the championship.

Manning completed two of his six passes for 19 yards. He was 0-for-3 on New York's first possession, including two passes that were knocked down by Lions linemen. Eddie Johnson's 31-yard field goal with 2:47 to play gave Detroit the win.

CHIEFS 24, BEARS 20: At Chicago, Larry Johnson showed glimpses of his old self, and Brodie Croyle hinted at what might be.

Back from a broken foot, Johnson ran for a touchdown on the opening drive, and Croyle made the most of limited time to lead the Kansas City Chiefs to a 24-20 victory over the Chicago Bears in the preseason opener Thursday night.

Johnson burst through the middle, past Brian Urlacher, for a 7-yard gain on the second play from scrimmage and finished the drive with a 5-yard run. He had 18 yards on eight carries. Croyle passed for 82 yards over two possessions, and Tyler Thigpen threw the winning 27-yard pass to Bobby Sippio with 1:08 left in the game.
