Tony Romo was a full participant in practice with the Dallas Cowboys on Wednesday for the first time since suffering his back injury.

Jason Garrett said Romo worked with the scout team and did some individual drills as well.

Romo is reportedly on track to have completed his rehab schedule ahead of Sunday's game against the Pittsburgh Steelers, but that doesn't mean he'll supplant rookie Dak Prescott.

"We just have to see where he is," Garrett said. "Tony's practiced four days over the last couple of weeks and has been involved in part of practices on each of those days. We'll do something similar with him today. He'll start in individuals and see how he does. He'll be working some scout-team reps like he did last week.

"We'll just take the situation day-by-day. We have a number of guys who are injured on the team, and that's what we do ... We will evaluate his situation day-by-day."
