Tony Romo unfazed by injuries, personnel moves

SAN DIEGO -- The Dallas Cowboys' two starting wide receivers, center and tight end are questionable for the regular-season opener.

The projected starters at guard have yet to play in a game at the same time.

The replacement center is really a guard who has had to snap the ball almost 600 times in training camp just to get comfortable.

But quarterback Tony Romo is undeterred about the injuries and uncertainty with the Cowboys' offensive personnel with the regular-season opener against the Super Bowl champion New York Giants looming on Sept. 5.

As the Cowboys ended training camp Tuesday, Romo was trying not to go bonkers regarding his lineup.

When the regular season starts, a good chunk of the projected starting lineup will not have played any preseason games together.

Wide receivers Dez Bryant (knee) and Miles Austin (hamstring) won't play again this preseason. Austin missed the first two games, too.

Tight end Jason Witten (spleen) played just three series this summer and could miss the regular-season opener.

Center Phil Costa is battling a stiff lower back. Guard Nate Livings (hamstring) just returned to practice Monday and is developing a chemistry with David Arkin, the man who replaced Costa. Then there's Mackenzy Bernadeau, the new guard, who is also trying to find some chemistry along the offensive line.

Tackles Doug Free and Tyron Smith are switching spots and learning new techniques.

"You got to have mental toughness," Romo said. "Everybody on the football team, at the end of the day, you have to be at your best, regardless of the circumstance, and that's your approach you got to take as a football team and as each individual."

He can't magically fix the injuries to the Cowboys' best players. He has to deal with what's left of the offensive roster, starting Saturday night against the St. Louis Rams.
