The Dallas Cowboys face the San Diego Chargers at Qualcomm Stadium at 9pm EST.

You can watch the preseason action here. 

Dallas enters Saturday's game banged up after a 3-0 victory against the Oakland Raiders in their first preseason game.

The Cowboys offense left head coach Jason Garrett aghast last week, and he called for tougher play from the entire squad. Reports have the first stringers playing into the second quarter against the Chargers. 

Dallas's offensive line was already hit with the injury bug this season, so center David Arkin was asked to take on snapping duties. The 6-foot-5 behemoth out of Missouri State had no major hiccups against Oakland, and could be taking snaps well into the second half tonight. The line will also miss left guard Nate Livings who is missing his second straight game. Livings was as huge pick up for Dallas during free agency, but is still working out a hamstring pull.

Quarterback Tony Romo will be without top receiver Miles Austin for the second straight week, and his favorite target Jason Witten is recovering from a spleen injury inflicted during the Oakland game. Look for Andre Holmes to repeat his performance against Oakland, when he grabbed three receptions for 40 yards to lead all Dallas receivers.

Stud first-round rookie safety Morris Claiborne will make his debut for the Cowboys after recovering from wrist surgery in the offseason and a sprained knee during camp. He may not start, but Dallas is eager to get him going. 

Like the Cowboys, San Diego missed the playoffs by a hair last season. They started their newest campaign on the right foot by defeating the Green Bay Packers 21-13 last week.

The minor victory proved costly as running back of the present and future Ryan Matthews fractured his collar bone and could miss the first week of the regular season. San Diego will turn to veteran Ronnie Brown and Curtis Brinkley, who earned42 yards and a touchdown off 11 carries against Green Bay. 

Veteran quarterback Philip Rivers finished 3-5 for 37 yards against the Packers, but only participated in four possessions. He will play longer into tonight's game.

San Diego's defensive front could give the ailing Cowboys line fits. Rookies Melvin Ingram and Kendall Reyes showed their chops against Green Bay. Ingram had two tackles and QB pressure that led to an interception, while Reyes recorded one tackle and three assists to go along with half a sack.

Prediction: River's is determined to bounce back from a poor showing in 2011, and will have his team ready to compete. Dallas' O-line is not at 100 percent, which will make Romo's defensive reads more difficult. 

Predicted Score: San Diego 27 Dallas 10
