IRVING, Texas (AP) -- Tony Romo is eager to help the Dallas Cowboys end their seven-game losing streak Sunday at Miami.

He just needs the final OK to be on the field.

Romo is expected to start against the Dolphins, though coach Jason Garrett is taking things day by day as his 35-year-old quarterback heals from a broken left collarbone.

Without Romo, the defending NFC East champions (2-7) went 0-3 with Branden Weeden starting and then lost four more with Matt Cassel under center. Weeden was cut on Tuesday.

"I don't think that anyone in this locker room thinks by any means that this season is over," Romo said Wednesday. "You lose enough games, sometimes it can creep in where it feels that way, and I don't think our team has not ever given 100 percent commitment. That's exciting to see. That's how you can turn it around."

Dallas has led or been tied in the fourth quarter in six of the seven losses. The Cowboys waived running back Christine Michael this week, leaving two rookie backups to Darren McFadden who have two career carries combined, both by Rod Smith.

Still, Romo says there's a chance to build some momentum with wins against a schedule that included Carolina, Washington, Green Bay and the New York Jets after the Dolphins game.

"You win one or two, and guys are committed to their craft and playing as hard as they are, good things can happen and happen quickly," he said.
