IRVING, Texas -- After losing inside linebacker Sean Lee for the season and a myriad of other injuries affecting the Cowboys, owner/general manager Jerry Jones seems to be changing his tune about whether the team can contend for a Super Bowl title this season.

After the Cowboys' 31-29 loss to the Baltimore Ravens on Oct. 14, Jones said he saw things that made him believe the Cowboys could contend this season.

But after losing Lee (toe), Jones had a different vibe.

"We’re going to have to adjust for him," Jones said. "... We’re going to have to make injury adjustments. I’ve said all along I think this team has an opportunity to be a contender, but the one exception that I made was, sitting as we’re sitting right now health-wise, injury can make a difference and does in the NFL."

Injuries pop up in the NFL all the time, but teams must overcome them to reach their goals. Losing a star player hurts badly and, with DeMarco Murray also injured, the Cowboys have two of their biggest playmakers out for Sunday's rematch against the New York Giants at Cowboys Stadium.

"Against this team, arguably the best team in the NFL, we wanted all hands on deck," Jones said. "It is disappointing not to have two players of that caliber. It’s been my experience when you do have a situation like this, others will step up. Others on the field at different positions will compensate. Like I said, we’ll give more to (Bruce) Carter and he’ll have to compensate and be a better factor."
