As Dallas Cowboys quarterback Tomy Romo recovers from back surgery, he is taking a measured approach to returning to game action.

Romo indicated Wednesday that he might not play in the Cowboys' Aug. 7 preseason opener against the San Diego Chargers, but he expects to see some action in exhibition games as he prepares for the regular-season opener on Sept. 7 against the San Francisco 49ers.

"You're constantly evaluating it and you're constantly, I don't want to say adjusting because you stick to the plan, but it's a progression," Romo said at the Cowboys' training camp in Thousand Oaks, Calif. "It's leading up to San Francisco. I am going to play in the preseason, obviously. I think it's important. The first game, we'll talk about it as we move into the weekend."

Romo practiced Wednesday and expects to be back on the field Thursday. He sat out Tuesday's practice as the staff monitors his recovery from the December back surgery.

"It's just a little unknown so you'd rather play it safe than be silly and just go out and do everything over and over again and all of a sudden have to sit out for a week or so," Romo said. "I think more than anything we're playing the long game and I think that's smart."
