OAKLAND, Calif. — Darren McFadden needed one series to show he's in midseason form for Oakland following a foot injury that cut his last season short.
Most of the rest of the first-team offensive players for the Raiders and Dallas Cowboys need plenty of work to get back to that level.
McFadden picked up where he left off last season by gaining 38 yards on Oakland's first three plays of the exhibition season and the Raiders went on to lose to the Dallas Cowboys 3-0 on Monday night.
"He was able to make some explosive gains," Raiders coach Dennis Allen said. "That's what we anticipate out of him. He's an explosive play-maker. We have to find ways to get him the ball and give him an opportunity to be explosive for us."
McFadden, who missed the last nine games of 2011 with a Lisfranc injury to his right foot, opened the game with a 4-yard run, an 18-yard reception and a 16-yard run to delight of the Raiders fans.
But Carson Palmer threw an interception to Gerald Sensabaugh on the next play for Oakland (tied for No. 23 in the AP Pro32) and both the Raiders and Cowboys (No. 15, AP Pro32) struggled to generate much of anything until the reserves took over in the second half.
"We made some mistakes and it cost us," Dallas quarterback Tony Romo said. "There will be some good stuff to evaluate and get better. We have to get better from tonight's game and we will."
Kyle Orton drove Dallas 67 yards on the opening drive of the second half to set up Dan Bailey's 33-yard field goal and that proved to be the only scoring of the night.
McFadden left after that first series and Palmer couldn't move the Raiders without him. Matt Leinart played the rest of a scoreless first half and completed six passes to undrafted free agent Rod Streater but couldn't put any points on the board.
Dez Bryant, who status was in question after leaving practice early Saturday because of hamstring tightness, came up with the only big play for Dallas' first-team offense when he made a good adjustment in the air for a 24-yard gain from Romo on the first offensive drive for the Cowboys.
That was the only first down in three series with Romo under center. Only two of Dallas' other 10 plays with Romo in the game went for more than 1 yard and both of those were on third-and-longs when the Cowboys couldn't convert.
But the Dallas defense did the job after the fast start by McFadden.
"We just had to settle down," Sensabaugh said. "Once we got settled down and everybody just kept doing their job, there weren't too many big plays coming after that. (Our) guys were able to make plays."
The play was sloppy all around as Dallas twice committed penalties on punts to prolong drives for Oakland and committed another before a botched snap on a field goal try.
The Raiders were unable to make the Cowboys pay for those mistakes as the first drive aided by two fourth-down penalties ended in a punt and usually reliable Sebastian Janikowski was wide right on a 47-yard field goal attempt after the third infraction.
Oakland had its share of mistakes as Chimdi Chekwa let a punt roll to the goal line instead of downing it at the 1 and receiver Jacoby Ford had a rough day all around.
Ford was stopped after a 4-yard return on the opening kickoff, had two passes from Palmer go through his hands, was the target on Palmer's interception and muffed a punt that rolled out of bounds to miss a chance at a return.
Even the replacement officials had their own problems as they spotted one ball outside the hash marks only to have Romo correct them.
The game also marked the first real action as a pro for Terrelle Pryor, the former Ohio State star quarterback who had no official plays as a rookie with Oakland. Pryor missed last preseason because he entered the league late through the supplemental draft and committed a false start penalty before his only play in the regular season.
Pryor completed 8 of 15 passes for 50 yards, was sacked twice and was quick to leave the pocket to scramble, running six times for 21 yards. He put Oakland in position to score but Eddy Carmona missed a 36-yard field goal wide right with 6:44 remaining. Pryor then threw an interception on fourth-and-26 in the final minute to end the game.
"I thought I played bad," Pryor said. "I just could've played a lot better and I will play better. I just played bad today."
