Tony Romo informed Dallas coaches on Wednesday that he is ready to play Sunday against the St. Louis Rams, a high-ranking Cowboys' source told ESPN.com's Matt Mosley. He suffered a broken pinkie finger on his throwing hand in a 30-24 loss at Arizona on Sunday, and Dallas medical staff believe that he will miss a month. Romo did not practice on Wednesday but did throw the ball on the side, and according to eyewitnesses, he was able to throw the ball with good velocity and appeared confident after throwing.
