GREEN BAY, Wis. -- Raiders quarterback Carson Palmer, having thrown four interceptions including one on the opening drive, thinks he was an offender of coach Hue Jackson's claim that some players were simply pressing and trying to do too much.

"I just need to be more patient, take what they give me and try not to score 14 points on one drive," Palmer said after a 46-16 loss to the Green Bay Packers on Sunday at Lambeau Field. "Take it one play at a time, take the shot if it's there, and if not, live for the next down, and I didn't do that."

Palmer completed 24 of 42 passes for 245 yards with four interceptions, none bigger than the one that got the Packers off and rolling. On Oakland's opening drive, Palmer was flushed to his right by Clay Matthews, didn't get enough on the ball and threw it directly to linebacker D.J. Smith.

A short time later, Ryan Grant raced 47 yards for a touchdown and the rout was on.

"You can't dig yourself that big of a hole," Palmer said. "You really can't dig yourself a hole at all, and for me to throw that interception was unacceptable."

It was only the beginning. With the Raiders trailing 24-0 in the second quarter, Palmer threw to Darrius Heyward-Bey on a slant pass that was read perfectly by cornerback Charles Woodson at the Raiders 25-yard line.

The Packers eventually scored on a 6-yard run by Grant to make it 31-0.

Just before halftime, Palmer looked toward Kevin Boss in the end

zone from the 14-yard line, with linebacker Robert Francois getting the interception. The last pick came just inside the two-minute warning on a deflection to Sam Shields.

The four interceptions tied a career high for Palmer.

"I'm disappointed in the four picks, and I told him so," Jackson said. "I think you have somebody who's pressing, trying to make plays for a football team. There were times we made some ill-advised throws and we've got to do a better job of taking care of the ball, and he knows that."

On the other side of the field, Packers quarterback Aaron Rodgers was doing everything Palmer was not, completing 17 of 30 passes for 281 yards, two touchdowns and a single end-zone interception on a terrific defensive play by Raiders safety Mike Mitchell, who outfought Jermichael Finley for the ball.

"You've got to give credit where credit is due. They're a good offense. Everybody in the league has experienced how good they are," safety Matt Giordano said. "They're a very good offense, but there were a lot of things we could have executed a little bit better to limit them."

Wide receiver Darrius Heyward-Bey finished with five receptions for 78 yards, and his 34-yard catch was the Raiders' longest play of the game, but he had three drops when the game was in its formative stages.

"Those are plays I wish I had, but I made up for it," Heyward-Bey said. "Some plays, that's what's going to happen."

During the CBS telecast, analyst Phil Simms, talking about the injury to running back Darren McFadden, referred to it as a "Lisfranc" injury, which is a season-ender in most cases and is an injury to a mid-foot joint that takes a long time to heal.

Houston quarterback Matt Schaub is out for the season with a "Lisfranc" condition.

"It's a sprained foot, Lisfranc, whatever you want to call it. Basically the same thing," Jackson said. "I think Darren will be back before the season's over."

What appeared to be an 82-yard fumble return by Kamerion Wimbley evaporated when replay officials ruled an Aaron Curry sack of Rodgers resulting in a fumble was actually an incomplete pass because the quarterback's arm was moving forward.

As it turned out, it wouldn't have been a touchdown anyway -- Lamarr Houston was called for clipping on the play.

Green Bay's Randal Cobb returned the second-half kickoff 50 yards to the Oakland 47, and although he may have stepped out of bounds, the play stood because the replay system failed.

"Clearly he stepped out of bounds, but they couldn't go in the booth and review it, they had to place the ball where it was," Jackson said. "That's the way it goes."

Woodson's interception was the seventh of the season, the fourth time he's had seven or more in a Green Bay uniform. In eight seasons with the Raiders, Woodson never had more than five interceptions in a season.
