In two series of work, Romo completed four of five passes for 80 yards and a touchdown.
"I thought he looked comfortable," coach Jason Garrett said at halftime. "I thought he looked like himself and moved around in the pocket. He made some good throws that looked like he saw the field well. He felt the pocket really well and looked comfortable moving the team."
Romo saw his first action since Dec. 22, 2013 in Week 16 against the Washington Redskins because of back surgery. He missed five of 16 practices in Oxnard, California, for training camp as he and the Cowboys worked through a schedule in which Romo got enough work but not enough to overdo it.
"It felt good," Romo said. "I thought it was great to get out there and help the football team and go through the checks and balances you have to do to get your team in a position to compete."
Romo had a 31-yard touchdown pass to Dez Bryant to cap his night.
"His mind was right, he was poised and went out there, knew what he wanted to do, and did it," Bryant said. "He wanted to show the world he is 9 and he's a baller."
