Romo informed Dallas' coaches on Wednesday that he is ready to play Sunday against the St. Louis Rams, despite breaking the pinkie on his throwing hand last weekend, a high-ranking Cowboys source told ESPN.com's Matt Mosley.
Cowboys owner Jerry Jones would love to see it happen.
Jones, making an appearance on 1310 The Ticket's Dunham and Miller show, confirmed there is a strong possibility Romo could play Sunday despite a broken pinkie.
"He very well could play," Jones said on 1310 The Ticket, adding the decision would probably be left up to coach Wade Phillips and Romo.
At practice Thursday, in which he participated, Romo was seen wearing a bandage on his injured right hand and appeared to have a splint protecting his pinkie. He has not spoken with the media after the extent of the injury was revealed.
Phillips has said Romo would not play if he's unable to practice.
"Tony is smart and will make he right decision," tight end Jason Witten said.
Romo broke the pinkie in a 30-24 loss at Arizona, and Dallas' medical staff said that he would miss a month. The injury did not require surgery. The Cowboys' biggest concern is that Romo would get hit again and injure the pinkie further, causing him to miss more time than initially anticipated and possibly require surgery.
Romo huddled with Jones, team vice president Stephen Jones, Phillips and the medical and training staff as the rest of the team practiced to discuss his prognosis.
Romo did not practice Wednesday but did throw the ball on the side with his fractured pinkie in a splint, and according to eyewitnesses, he was able to throw the ball with good velocity and appeared confident after throwing. The session was not open to reporters.
There is no assurance he can protect the ball, take a snap or deliver the ball accurately under game conditions.
Brett Favre, who has started an NFL-record 258 consecutive regular-season games, told ESPN on Tuesday that he called Romo and encouraged him to try to play.
"The only thing I said was, it's worth trying [to play] if you can deal with the pain and can function good enough with a splint,'' Favre said. "If not, don't try.''
Favre has played through a fractured thumb in the past.
After saying he'd try to play, Romo's streak of 32 consecutive starts is now in the hands of others.
