Was Tony Romo's surgery serious?

OXNARD, Calif. -- Tony Romo made his return to the Cowboys' practice fields during the Sunday morning walkthrough after missing the entire offseason of workouts while recovering from surgery to remove a cyst from his back.

After Romo's surgery, the team said he would recover in about a month, but it took longer than that, and team officials said his time away from the practice fields was precautionary.

So was the surgery, described as minor, more serious than the Cowboys let on?

"The way it was described to me was a ‘micro’ procedure, is how it was described to me," coach Jason Garrett said Sunday. "I was around when Troy Aikman had a severe back injury and had surgery -- I think it was in late June -- if you remember, I think it was the '93 season, if I’m not mistaken. Relatively speaking, and you guys know I don’t like to compare things, they describe this as a micro procedure as opposed to some of the other back injuries that guys have to deal with. So you got to err on the side of caution in the offseason with all these guys, particularly coming off any kind of procedure they might have. But again, it’s July 21st. It’s good to have him back on the field."

Romo said a few months ago the cyst wasn't cancerous and he didn't even know how big it was. He noted it gave him discomfort when he moved around, and his recovery from surgery delayed him from getting in shape for training camp.

Garrett said Romo is about a pound more than his prescribed playing weight. During OTAs he was listed at 236 pounds, but he apparently is closer to 230 pounds now.
