Alex Barron: Got to work on some things

LANDOVER, Md. -- One of the biggest plays in Sunday night's 13-7 Redskins victory over the Cowboys was right tackle Alex Barron's holding call that wiped out a game-winning touchdown pass.

Barron, who was called for two holding penalties in the second half and three overall, had a choke hold on Redskins pass rusher Brian Orakpo as quarterback Tony Romo completed a touchdown pass to Roy Williams to end the game.

The penalty on Barron with time expired ended the game.

Barron said he didn't want to talk about the penalty and whispered, "Got to work on some things, man."

Barron was starting because Marc Colombo was out after undergoing knee surgery during training camp. Colombo didn't practice leading into the Redskins game, but coach Wade Phillips said Colombo should practice this week.

The penalty set off a range of emotions by the Cowboys.

Jerry Jones was sitting in a luxury suite thinking Williams had scored a touchdown.

"I thought we had pulled it out," Jones said. "I was sitting over there just giving a fist pound and feeling real good about it and was just stunned when I saw the flag."

Phillips was stunned.

"I've never seen that happen," Phillips said. "You score a touchdown and get a penalty and the game is over."

Said Bradie James: "We scored. But I guess we had a penalty so we didn't win. We knew it was going to be a 60-minute game and that's what it was."

Said Romo: I thought we won and then 10 or 15 yards after running away, I noticed people weren't coming out on the field. It's hard to swallow. It's a tough one to take."

The Cowboys have two players that have problems with holding calls.

According to ESPN Stats and Information, Barron has been called for 10 holding calls, the most in the NFL since 2009.

Center Andre Gurode has been called for the third most with six.

Barron was asked about his issues overall and he said, "We've got to work on some things."
