The Dallas Cowboys are being careful with Romo during the early part of training camp and effectively allowing him to set his schedule. Romo sat out of the second day of camp to be ready for the first two full-padded workouts before Monday's off day.

The plan is for Romo to take all of the snaps in practices for Wednesday and Thursday with another off day scheduled for Friday. With Tuesday's practice set to have competitive two-minute drill situations, the Cowboys wanted to limit Romo's work.

He took part in the team part of the morning walkthrough.

"He hasn't had any setback, but the biggest thing that we talk to Tony about and really all of our players about is honest feedback," coach Jason Garrett said. "We recognize that you're a tough player. I saw what you did against the Redskins last year. You've just got to tell us how you're doing, how it's going and make sure we handle it the right way each and every day. There's an old adage in football: A day off can be really valuable and two days off can be life changing."

In the meantime, on the defensive line the Cowboys defensive end DeMarcus Lawrence suffered an ankle injury during afternoon drills and had to be carted off the field. Lawrence suffered the injury while going up against Pro Bowl left tackle Tyron Smith. The Cowboys are hoping it is not a high ankle sprain, otherwise this would end up being a huge blow to an already thin defensive line.

The bright spot on the Cowboy's defensive line has to be defensive tackle Henry Melton's progress in his return from the knee injury. There have been flashes of the quickness and explosiveness that helped Melton, who started his college career at Texas as a tailback, earn a Pro Bowl bid while playing for Cowboys defensive coordinator Rod Marinelli in 2012.

Garrett said Melton looks good in non-contact individual drills but must work on his "contact balance," which is to be expected for a player coming off a major knee injury.

Injuries and uncertainty surrounding Tony Romo and the Cowboy's defensive line continue to be major concerns out in Dallas training camp.
