OXNARD, Calif. – Head coach Jason Garrett provided some insight Monday on players and themes that stood out to him from Sunday's practice and scrimmage.

It's rare Garrett singles anyone out, but he talked first about an undrafted receiver that's turned a few heads early on in camp. Garrett said Chris Boyd consistently makes plays when he's given an opportunity down the field.

On Sunday, Chris Boyd used all of his 6-4 frame to snag a deep ball, and it seems like he comes up with one or two highlight plays every couple practices.

Garrett also singled out Martez Wilson as a pass rusher that showed up consistently throughout the day. Wilson's strong day was most evident on a strip sack of Brandon Weeden, when he knocked the ball out, scooped it up and returned it for a score. Garrett also said he liked what Terrance Williams was able to do on a deep ball he had to stop and run back to retrieve.

Most importantly, Garrett thought the communication was improved and the offensive line played physically up front.

"That's really something we're looking for as a team," Garrett said. "I don't want to point too many guys out, but it showed up. I thought the overall energy was really good. There was some good contact being made."

Now, Garrett said the trick is to take the intensity from that practice and have it continue the rest of the week leading up to the San Diego preseason game.

"You've had success, you've had adversity, you've had a spirited practice, you have a non-spirited practice, the expectation for all of us is to come out here and practice at a higher level and do it better," he said. Yesterday was a really good learning experience…I think we took a step forward. Practice intensity was excellent. Competitiveness was excellent. The best teams I've been around practiced that way. I think we're developing that."

Here are some more hits from Garrett's press conference and early Monday notes:

• Garrett said the Cowboys are looking to add someone at cornerback. They're short at the position with Morris Claiborne hurt and Brandon Carr out for personal reasons. They brought in former Ole Miss cornerback Charles Sawyer and he may be an option later on, but he failed a physical.

• When the Cowboys went out for their special teams walkthrough, linebacker Rolando McClain was back on the field. Garrett said he's hopeful McClain can go for today's afternoon practice.

• As far as the other injuries, Garrett said Jakar Hamilton won't practice and Barry Church's status is up in the air, while J.C. Copeland and Ben Gardner will practice more. Garrett's hopeful Claiborne can do something today, but he doesn't anticipate a lot today for the corner. Wide receiver Dezmon Briscoe will also be monitored day by day. Briscoe, Hamilton, Church and McClain all got dinged up Sunday.

• Tony Romo, meanwhile, is expected to practice. Garrett said he thought Romo's body responded well to the practice and it appeared he bounced back well Monday morning. As for the interception to Orlando Scandrick, Garrett said there was poor communication and has to do a better job preserving that opportunity when the ball's inside the 35-yard line and Dna Bailey has a chance.

• The Cowboys will start their preparation for San Diego tomorrow, according to Garrett.

• Sunday provided a good opportunity for guys like Copeland and Ahmad Dixon, who are physical players that show up more with pads on. Garrett said Dixon in particular is a physical player who hopefully will show up on special teams, and preseason games will highlight what they do best. He also said it was good seeing Copeland strike the linebackers Sunday.

• The Cowboys added guard Wayne Tribue. Garrett said the Cowboys worked him out last year and wanted to give him a shot but will work him in slowly. [embedded_ad]

• Tonight's practice is later than normal. Garrett said that's just to change up the schedule. It would probably be even later, but with no lights, they pushed it back as far as possible.

Garrett described Dan Bailey's training camp as excellent, and he said that continued Sunday. "He works very hard at it, and he just has a poise and a focus about him that I haven't seen from many guys at his position," Garrett said.

• The extra points in the preseason will be moved back to the 15-yard line, and Garrett likes that the league's using the time before the regular season to test new ideas out.

"We're going to take a look at it and see if we like it or not," he said. "If we don't like it, then we'll look to the next best decision. We'll be ready for it. I think it's good for those guys to get a look at it in practice before they have to do it on Thursday."
