EAST RUTHERFORD, N.J – Geoff Schwartz hasn't played a full football game since Jan. 4, when he played right guard for the Kansas City Chiefs in a 45-44 loss in Indianapolis in an AFC Wild Card Game.

"I think I can do it," Schwartz said today. "Until I do it, I won't really know. I feel pretty confident in my ability to do it. Like I said yesterday, I have done it before, when I haven't played very much and I had to start games. I did it last year. You just find ways to get through it. I am a veteran, I can do it."

The Giants have still not said where Schwartz will play. He played left guard before dislocating his toe in a preseason game, and has experience at right guard and tackle. Justin Pugh, who has started every game at right tackle, did not practice for the second straight day because of a quad injury. The coaches have been vague when asked about offensive line staffing for Sunday's home game against the Dallas Cowboys.

"Two or three guys are rotating through there, rotating out there and rotating inside," coach Tom Coughlin said.

"We have some guys moving around right now competing for spots," offensive coordinator Ben McAdoo said. "Anytime that you have competition, it's a good thing. It's a good thing for your football team, it's a good thing for that unit and it's a good thing for the individuals. … You roll them in there. Whoever has the best week of preparation plays."

When the Giants take the field Sunday night, it will be three months and a day since Schwartz last played in a game. But he believes he can help boost a line both in the run game and pass protection.

"Every day that I am out there I am able to work on my technique," Schwartz said. "That is what I need most at the moment is technique work. From that standpoint, I thought today went well. I was pretty pleased, every day is getting better. That is what I am looking forward to."

• Defensive end Mathias Kiwanuka (knee) joined Pugh, defensive tackle Cullen Jenkins (calf) and linebacker Jacquian Williams (concussion) on the list of players who did not practice. In recent weeks, Kiwanuka has worked Wednesday or Thursday, but not both days.

"(Williams) was out running on the side," Coughlin said. "We'll see what the results are like."

Last week, Mark Herzlich played many of the snaps that normally would have gone to Williams.

"I thought Mark played with a lot of passion," defensive coordinator Perry Fewell said. "I thought he played with a lot of heart. He made some football plays for us in the football game. He brought some toughness to the defense, I thought."

Spencer Paysinger could see more playing time vs. Dallas. When the teams met last month, backup tight end Gavin Escobar caught two touchdown passes.

"Spencer is a little more athletic," Fewell said. "We would probably use Spencer in some of the passing situations."

• Cornerback Dominique Rodgers-Cromartie (back/hamstring) practiced fully

• The Giants have lost their last three games to Dallas and trail in the all-time series, 60-49-2. The Cowboys are 3-1 in MetLife Stadium against the Giants.
