Tony Romo practices with hand injury

IRVING, Texas -- Tony Romo was limited in his first day of practice after suffering a bruised right hand against Philadelphia, but the Dallas Cowboys quarterback continues to maintain he will play Sunday against the New York Giants.

"It's continuing to improve day by day," Romo said on a conference call with the Giants' media. "I was able to do some things with the ball we weren't sure about. It should be good to go."

Coach Jason Garrett was coy about Romo's availability, but said, "he seemed fairly functional with the stuff he was able to do."

Stephen McGee took some of the first-team snaps with Romo being limited.

"It's still early," Garrett said. "We hope that he progresses. He has progressed since the game, so we'll see how he responds to the work today and hopefully he'll do more work tomorrow and get himself ready to play this game. But we have to be ready for all alternatives."

Romo wore a glove during the stretching period of practice, telling the Giants' media it was to keep compression on the top of his hand, which remains swollen. During the portion of practice that was open to the media, he did not wear a glove to throw passes.

"I thought he did good," tight end Jason Witten said. "I thought he was throwing the ball well. I couldn't tell any difference from a normal day."

Romo played through a broken rib earlier this season and an assortment of injuries during his career.

"He does a good job of not allowing those things get in the way of what we need to do," Witten said. "You'd probably have to ask him the details, but on the receiving end of it, he was as good as he always is."

Said outside linebacker DeMarcus Ware: "To have your starting quarterback out there, it's sort of a warming feeling. ... I think he's a warrior. He's going to get out there and play and be the leader that he needs to be for us."

Romo wasn't the only injured Cowboys player.

Ware, Pro Bowl nose tackle Jay Ratliff and inside linebacker Sean Lee did not attend practice.

Ware (stinger) and Ratliff (ribs) were limited last week with injuries so missing practice Wednesday is not a surprise.

Lee, who suffered a hamstring injury during the Eagles game last Sunday, was sent home Wednesday because he was sick. Lee said Sunday that he expects to play against the Giants.

"We did not think that [hamstring] was an issue," Garrett said. "He didn't practice because of the illness."

Also, safety Danny McCray (ankle) did not practice, but he planned to do some running and maybe return to a session on Thursday.

Nose tackle Josh Brent (knee) returned to practice for the first time in about a month.
