IRVING, Texas — 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 at quarterback. 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 losses, but has dealt with issues on and off the field. There has been drama surrounding Dez Bryant and Greg Hardy, but also some questions about the offense. 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 includes Carolina, Washington, Green Bay and the Jets after the Dolphins (4-5).

“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.

Dallas is only 2½ games out of first place in the division. Asked if he thinks more about the team’s 2-7 record or being that close to the NFC East lead, Romo said, “I don’t think about anything other than beating the Dolphins this week.”

During the seven-game skid, Dallas has failed to score a touchdown in three games. The Cowboys are tied for 30th in the league in points scored after ranking fifth last season. That was when the backfield included Romo for the entire season and the NFL’s leading rusher, DeMarco Murray, who left for Philadelphia via free agency. Bryant also missed five games season because of injury.

Weeden averaged 222 passing yards in his three starts with one touchdown pass. Cassel averaged 202.3 passing yards with four touchdown passes.

In Romo’s one full game, he threw for 356 yards and three touchdowns in the season-opening, 27-26 win over the New York Giants.
