OXNARD, Calif. — The Cowboys defense suffered another blow. Rookie defensive end DeMarcus Lawrence has a fractured right foot and is expected to miss at least 8-12 weeks, according to a source.Lawrence underwent X-rays after being injured in practice Tuesday evening.The second-round pick went down to the ground and grabbed his right foot during a drill against left tackle Tyron Smith, and Lawrence had to be carted off the field.Asked after practice if he was concerned, owner Jerry Jones said: “I want to see the X-ray. But the answer would be yes. Hopefully, it will be OK.”Said defensive coordinator Rod Marinelli: “You don't like to see that. You wait and see what it is, but a guy goes down for a little bit, it's not good. But you just have to go on. It's next man up.”The Cowboys traded up in the draft to get Lawrence, who had been expected to fill the Cowboys’ void at defensive end after DeMarcus Ware went to the Broncos. He stated lofty expectations for his rookie season, as well, saying he’d like to have at least 10 sacks.Lawrence wasn’t the only player who left practice early. Linebacker Rolando McClain didn’t finish practice because of a stomach virus.Romo sitsQuarterback Tony Romo sat out Tuesday afternoon’s practice, but team officials say there is no concern about the star quarterback’s health.“He’s 100 percent,” Jones said. “He’s just being real smart and sensitive about having come off the back surgery. He’s certainly not losing any ground from the standpoint of opening up against San Francisco [on Sept. 7].”The Cowboys were off Monday and Romo went through the morning walk-through Tuesday before missing the padded practice. He is expected to practice Wednesday and Thursday.Romo was declared full-go at the start of camp, but the Cowboys have limited his workload. He is coming back from surgery to repair a herniated disk in December, his second back operation in the past year.Vice president Stephen Jones had said earlier in the day he expected Romo to practice, but coach Jason Garrett revealed at his press conference that Romo would sit out.Romo was also held out Friday afternoon.“There’s an old adage in football, a day off can be really valuable,” Garrett said. “Two days off can be life-changing, so when you get in this kind of a situation, we had yesterday off, got some good work this morning in the walk-through, some mental work of some of the different situations we’re working on. “Off this afternoon and hopefully back at it tomorrow.”Cowboys territoryJerry Jones thought somebody was joking with him when he heard that Oakland Raiders owner Mark Davis met with San Antonio officials to discuss a potential move of the team, according to a report in the San Antonio Express-News.“I don’t make a lot of this. At all,” Jones said. “It’s not ... something I necessarily would be familiar with. Again, my interest in San Antonio is because how important it is to the Cowboys and our history of having our training camp there and the fact that we’ve got such a tremendous fan base in San Antonio.”The Cowboys last spent part of their training camp in San Antonio in 2011. In order for the Raiders to be allowed to move, 24 of 32 owners would have to approve it.Lee talksLinebacker Sean Lee spoke for the first time since his season was lost to a torn ACL suffered during organized team activities in May. Lee is rehabbing with the team in California and hopes to begin running in five weeks.Lee expressed frustration about being sidelined yet again with an injury, but is confident he’ll be able to return strong for the 2015 season.
