IRVING, Texas – Jason Garrett calls the availability of safeties Gerald Sensabaugh and Barry Church as “day to day,” but the Cowboys are likely to be without Sensabaugh because of a right calf strain Sunday versus Tampa Bay.

Church has a bruised quadriceps and appears to be more hopeful, but it will be an issue.

The Cowboys are not looking at adding a safety to the 53-man roster or the practice squad just yet, and there’s hope that rookie Matt Johnson can get back on the field soon. But it doesn’t look like it will happen this week.

Johnson missed most of training camp with a hamstring injury and hurt his other hamstring on Aug. 25 versus St. Louis in the preseason. He has not practiced since.

“I’ve had tweaks in the past where they’d go away in a day,” Johnson said. “That’s what’s really frustrating. That’s what we’re trying to figure out why it’s happening.”

How?

“We’re looking at everything,” Johnson said. “Just past history, what I’m doing, what I’m eating, my daily diet, when I’m stretching if I shouldn’t stretching, doing enough stretching, yoga. Just everything to see what’s going on.”

So far the Cowboys' only answer is rest and rehab.

With only two safeties on the roster that are 100 percent healthy, Johnson has an urgency to return.

“Obviously two guys going down at safety and not knowing what they’re going to be doing this week, I’m trying to get back as fast as I can,” Johnson said. “But whatever (the medical staff) says, goes.”
