Tony Romo took pregame injection

EAST RUTHERFORD, N.J. -- Dallas Cowboys quarterback Tony Romo took a pain-killing injection before Sunday's 31-14 loss to the New York Giants because of the bruised right hand he suffered last week.

Romo went into the locker room early in pregame warm-ups to take the shot.

"It was mild," Romo said when asked if that affected his ability to handle the ball. "I mean, just sometimes it was good and sometimes it was just a little bit whatever. I think you're just not used to doing it. That's the biggest adjustment more than anything, but looking back I kept throwing on the sideline to get that feeling and I thought we did alright."

Romo said the shot did not affect his whole hand and the injury did not "have a bearing on the outcome of the football game." He took only one snap from center during the week of practice.

On Sunday, Romo finished with 289 yards passing, completing 29 of 37 passes. He threw two touchdowns to Laurent Robinson and was intercepted once. He was sacked a season-high six times, including one that led to a fourth-quarter fumble.

Romo needed pain-killing injections for several weeks after suffering a fractured rib and punctured lung in a Week 2 win at San Francisco.
