GREEN BAY, Wis. - The Green Bay Packers lost their unbeaten preseason record in a 21-13 loss to the Jacksonville Jaguars at Lambeau Field on Thursday night.

After sputtering under starting quarterback Byron Leftwich, the Jaguars’ offense woke up when backup David Garrard entered the game early in the third quarter. Playing against the Packers’ second-string defense, Garrard played two series and led the Jaguars (2-1) to two touchdowns.

Garrard opened with a 7-play, 45-yard drive capped by a 1-yard touchdown run by LaBrandon Toefield. He came back with a 25-yard touchdown pass to former Oregon tight end George Wrighster to put the Jaguars ahead 14-10 late in the second quarter.

Garrard was 6-for-7 for 97 yards and a touchdown before he was replaced by third-string quarterback Quinn Gray, who played despite the death of his father, a renowned high school football coach in South Florida, Thursday morning.

Leftwich was 6-of-16 for 67 yards, often dodging pressure from the Packers’ defensive line — the Jaguars were missing two starting offensive linemen — and overthrowing open receivers several times.

Brett Favre and the Packers’ first-string offense got off to a slow start due in part to shaky play from two of their most important rookies, wide receiver James Jones and running back Brandon Jackson.

On third-and-10 late in the first quarter, Jones caught a ball from Favre that appeared to be good for a first down, but was stripped of the ball by cornerback Rashean Mathis and the ball was recovered by Williams.

Later Jones drew Favre’s ire when he cut off a shallow crossing route and Favre threw incomplete. Favre motioned emphatically to Jones after the play.

Jackson, a second-round pick out of Nebraska, struggled to find holes, carrying 11 times for only 20 yards.

Favre was 14-for-20 for 130 yards and led the Packers to a field goal before he was relieved by Aaron Rodgers just before halftime. Rodgers immediately led the Packers on a 9-play, 73-yard drive, ending with a 1-yard touchdown run by Jackson.

A bigger concern for the Packers was the status of Pro Bowl wide receiver Donald Driver, who was taken to the locker room just before halftime with an injury to his right foot.

Notes:Gray defended his decision to play on the day of his father’s death.

Otis Gray, who coached for 13 seasons at Dillard High School in Fort Lauderdale, Fla., died from complications due to colon cancer. He was 62.

“This is a sad day for me and my family,” Gray said in a statement issued by the team before the game. “I’ll play tonight with a heavy heart, but I want to play because that is what my dad would want me to do. I want to play for my dad and my family. Tell my family I love them and I’ll be home soon.”

Gray was 3-for-5 for 44 yards against Green Bay.

“Obviously, I told him, ‘Listen, we can get you home right away.’ We knew that he was ill, and we had talked about after the game him going down there and missing the next couple of days,” Jaguars coach Jack Del Rio said. “Unfortunately, his father passed and so he’ll go be with his family now, and we’ll support him the best we can.”

In 13 years at Dillard, Otis Gray had a 107-54 record and produced several college and NFL players. Dillard made the playoffs from 1983-90, winning state championships in ’86 and ’89.

Saints 30, Chiefs 7

KANSAS CITY, Mo. — With one preseason game to go, Drew Brees was already showing off his Pro Bowl form.

The same cannot be said of the Kansas City Chiefs, whose murky quarterback picture was only muddied further Thursday night as Brodie Croyle struggled and a nearly perfect Brees led the New Orleans Saints to a dominating 30-7 victory.

Playing in all but one series in the first half, Brees hit 17 of 19 passes against the first-team defense for 182 yards and one touchdown. One of his passes was a beauty of a downfield dart that David Patten dropped. His quarterback rating when he retired for the night was 124.1 — a sharp contrast to the 15.1 of Croyle.

The second-year pro, battling veteran Damon Huard for the starting job, was only 5-for-17 for 45 yards. Hurried and harried by a New Orleans defense that frequently beat the Chiefs’ offensive line, Croyle was also sacked twice and threw his third interception in three outings.

This game was viewed as a golden opportunity for him to wrest the job away from Huard, who was held out with a sore calf.

But instead of seizing his chance, Croyle seemed to help make the case for Huard, a 34-year-old career backup who played well last year when Trent Green was injured.

In three preseason games, the Chiefs (0-3) have scored only 29 points. The defense has scored eight.
