Don't worry about Tony Romo.

That's the message from the Dallas Cowboys quarterback himself, who has absolutely no concerns about making it through a 16-game season after his second back surgery in as many years.

"There's no question in my mind, not only am I going to be able to make it through 16 games, I'll make it through another five years," Romo said Wednesday on KRLD-FM (via the Forth Worth Star-Telegram).

Romo underwent surgery to repair a herniated disc in December, an injury that kept him out of Dallas' Week 17 loss to the Philadelphia Eagles. Romo has been throwing, running and lifting weights and has set next month as his goal to be back to full health.

"Backs eventually just continue to get better and better and better, and all of a sudden you're 100 percent," said Romo, who showed up in NFL Network's "Top 100" countdown on Wednesday. "We're coming up on that pretty soon. Within the next month, there's no question we'll be 100 percent. Hopefully it's in the next week or two, which is a viable and serious time that it could happen in.
