FRISCO -- Dallas Cowboys quarterback Tony Romo hasn't technically rejoined practice, but that didn't stop the veteran signal caller from throwing a few passes during the portion of Cowboys workout open to the media.

Romo was in shorts and a T-shirt while the rest of the team was in full pads, preparing for Sunday night's showdown against the Philadelphia Eagles.

He threw several passes during the warm-up portion of practice, known as pat and go. And during individual drills for quarterbacks, he threw more passes, including some on the run.

It's been nearly nine weeks since Romo suffered a compression fracture of the L1 vertebrae in his back on the Cowboys’ first drive of the third preseason game against the Seattle Seahawks.

Romo won't play Sunday against the Eagles with rookie quarterback Dak Prescott getting the start. Prescott has been at the helm for the Cowboys’ impressive 5-1 start.

Cowboys Head Coach Jason Garrett confirmed that Romo would not be practicing fully with the team just prior to the workout.

"He'll just continue with his rehab," Garrett said. "We'll just take it day by day, but he's had some good days of rehab lately."

Cowboys owner Jerry Jones said a couple weeks ago that there's no timetable for Romo's return.

Garrett would not say if Romo could return to practice later in the week.
