SAN DIEGO (AP) -- It didn't take long for Danny Woodhead to remind the San Diego Chargers and their fans of what they missed most of the 2014 season.

Woodhead scored on an 8-yard run in his first game since September and the Chargers, whose owner has angered fans by exploring a move to Los Angeles, beat the Dallas Cowboys 17-7 on Thursday night in an exhibition opener.

Woodhead scampered through a big hole provided by the rebuilt line to cap San Diego's first drive and give the Chargers a 7-0 lead midway through the first quarter. He suffered a season-ending broken right ankle in the third game last year.

"It felt great," he said. "It's been a long process. I feel really good. The line blocked great. It was great to get out there and get in the end zone."

Said quarterback Philip Rivers: "It was awesome. He knows how I feel about him and how the team feels about him after last year."

The game was played two days after Carmen Policy, who is spearheading stadium efforts in Carson, told NFL owners that "the Chargers and Raiders are committed to Los Angeles." The Chargers, owned by the Spanos family, walked away from negotiations for a new stadium in San Diego in mid-June and are focusing on trying to move to Carson along with the archrival Oakland Raiders.

The Cowboys had two fumbles in the first half, including one by backup quarterback Brandon Weeden that was recovered by Patrick Robinson to set up Woodhead's score.

"I think the stuff we need to work on is obvious," Cowboys coach Jason Garrett said. "It's about the ball, the ball, the ball. We didn't take care of it there."

The Cowboys tied it at 7 when undrafted rookie Gus Johnson scored on a 5-yard run early in the second quarter. Johnson, looking to prove he can make it after the top three candidates to replace NFL rushing champion DeMarco Murray were hurt, left with a shoulder injury in the third quarter.

Coach Jason Garrett said he thinks it's a separated shoulder.

"He was taking advantage of his reps," Garrett said. "That was a good opportunity for him with three other backs not playing in the ballgame."

San Diego went ahead 14-7 when Branden Oliver scored on a 10-yard run just before halftime.

San Diego's Nick Novak kicked a 52-yard field goal in the fourth quarter.
