Indianapolis ? Yao Ming may stand 7-foot-6, but he’s already experiencing the growing pains most NBA rookies do.

Yao, the No. 1 overall pick in the June 26 draft, failed to score, had two rebounds, was called for three fouls and made little impact for the Houston Rockets in a season-opening 91-82 loss to the Indiana Pacers on Wednesday night.

“I learned that I still have a lot to learn, and I’m just a rookie,” Yao said through an interpreter. “It’s a very long road and it’s difficult.”

Jermaine O’Neal scored 24 points and had 10 rebounds and Ron Artest added 20 points for Indiana, which overcame a career-high 39 points from Houston’s Steve Francis.

Yao played only in the second and fourth quarters, turning the ball over the first time he touched it when Jeff Foster stripped him of it, the first of his two turnovers. The Pacers led 71-62 at the start of the fourth quarter when Yao was reinserted for starting center Kelvin Cato, who grabbed a career-high 17 rebounds.

Yao missed his only shot, a turnaround 12-footer over Foster. He received mild applause from the crowd at Conseco Fieldhouse.

“I didn’t feel good to sit on the bench and watch my teammates losing,” Yao said. “Of course, I want to contribute.”

Yao said he’d have to keep reminding himself that he would make mistakes like any rookie and still had to adjust to different rules and a faster pace.

Houston rookie Yao Ming defends Indiana forward Ron Artest during the second quarter of Ming's first regular-season NBA game on Wednesday in Indianapolis.

Coach Rudy Tomjanovich said it would take time for Yao to adjust to new surroundings.

“The guy’s been here 10 days. He’s just trying to get acquainted with our offense, our defense,” he said. “We’re happy with him. It’s going to take some time get acclimated.”

Francis, who was 13-of-28 from the field and made 12 of 14 free throws, scored 10 points in the fourth but couldn’t get the deficit under double figures until the final minute. He said Houston needed to be patient with Yao’s progress.

“It’s only his first game,” he said. “He didn’t play particularly well. Sometimes that happens in your first game. It’s a learning tool for him and also for us. We don’t want to focus on what one guy did.”

Cuttino Mobley added 22 points.
