EAST RUTHERFORD, N.J. –** Geoff Schwartz is on track to make his 2014 debut Sunday night vs. the Dallas, but where exactly he will line up remains a mystery.

Because Schwartz has started at both guard and tackle in his career, the six-year veteran is a candidate to start at several positions. He wouldn't hint where that might be on Sunday.

"I just moved around," Schwartz said. "I want to see where my best fit is for this week and moving forward. … I have played enough now where I can hopefully play anywhere and be okay. I'm sure we will narrow it down as the week moves forward."

Schwartz, who was the starting left guard before his injury, is presumably a candidate at either guard position, where veteran John Jerry (on the right side) and rookie Weston Richburg have been the starters. Right tackle Justin Pugh left early in the loss to San Francisco because of a quad injury that forced him to miss practice today.

Including left tackle Will Beatty and center J.D. Walton, the Giants have started each of the same five offensive linemen in their first 10 games. But that doesn't mean the group will be intact for an 11th game. Asked about maintaining continuity along the line, coach Tom Coughlin said, "that would be a reasonable expectation, but at this point in time, we're trying to be the best that we can. We'll do whatever we have to do to get it that way."

Coughlin said little about Schwartz except, "We activated him. I would expect that he would be ready, I hope."

Schwartz returned to the practice field earlier this month, but this is the first week he is working knowing he will play.

"I felt good today," he said. "It was good to get back out there and work with the offense a little bit and get in game plan mode. Things went well from the perspective of my toe and I feel good.

"I'll be fine. I have done this before. I have played sometimes sparingly and then had to play right away, like I did last year. You find ways to do it, and I'll be fine."

Schwartz has been in the offensive line meetings all season and he's been studying opponents as if he would be blocking them on Sunday.

"I have been treating every week like I normally do mentally," Schwartz said. "I am not the most athletic guy in the world, so I have to know where people are going to be. Film is a big thing of mine."

Schwartz has been intently studying the Cowboys' defense this week and like everyone else on the Giants, is impressed by what he's seen.

"They are a defense that plays extremely hard," Schwartz said. "They bought into their system, and they are getting the most out of their guys. Their defensive line, especially, they move a lot. They have linebackers that can run and make plays in the passing game. Just like we saw the first time around, we are going to get a lot of movement from them. They are going to bring it, and we are going to have to be ready for it."

• In addition to Pugh, linebacker Jacquian Williams (concussion) and defensive tackle Cullen Jenkins (calf) did not practice.

Jenkins said he participated in the pre-practice walk-thru before moving to the side to work on his own.

"It's getting a lot stronger," said Jenkins, who has missed two of the last three games. "It's just day-to-day. We'll wait to see how it responds to the work from today, if it gets sore or not. You just keep trying to push forward." * Defensive end Mathias Kiwanuka (knee) was limited. Cornerback Dominique Rodgers-Cromartie (back/hamstring) practiced fully.
