OAKLAND, Calif. — Darren McFadden needed one series to show he is in midseason form for Oakland after 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 seemingly need plenty of work to get back to that level.

McFadden accounted for 38 yards on Oakland's first three plays of the exhibition season and the Raiders went on to lose to the Cowboys 3-0 Monday night.

McFadden, who missed the last nine games of 2011, opened the game with a 4-yard run, an 18-yard reception and a 16-yard run.

"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 playmaker. We have to find ways to get him the ball and give him an opportunity to be explosive for us."

Kyle Orton drove Dallas 67 yards on the opening drive of the second half to set up Dan Bailey's 33-yard field goal that was the only score.

"We made some mistakes and it cost us," Dallas starting quarterback Tony Romo said. "There will be some good stuff to evaluate and get better."

Notes

• Louisiana State Police investigators have found no evidence the New Orleans Saints or general manager Mickey Loomis — a former Seahawks executive — rigged Superdome wiring so opposing coaches' radio communications could be intercepted.

The investigators have been working with the FBI since the eavesdropping allegations surfaced in news reports in April.

• Tennessee Titans quarterback Jake Locker, a former Washington Huskies standout, will get his first start of the exhibition season Friday against Tampa Bay.

• For receiver Chad Johnson, a weekend confrontation with his wife has led to repercussions beyond a misdemeanor charge and NFL unemployment.

VH1 pulled from its schedule the reality series "Ev and Ocho," starring newlyweds Johnson — formerly known as Chad Ochocinco — and Evelyn Lozada.

The Dolphins terminated Johnson's contract Sunday, about 24 hours after he was arrested in a domestic-battery case involving Lozada, who is on the reality TV show "Basketball Wives."
