Playing for the first time this preseason, Duncan scored 10 points in a 107-89 exhibition victory over the Greek club Olympiakos. He was sporting a bulky brace on his left knee, one the 33-year-old perennial All-Star said he's picked out for the season.
Duncan is coming off a disappointing season in which his knees began wearing down well before the Spurs lost in the first round and made their earliest playoff exit since 2000. The Spurs are taking it easy with their franchise star, who took an extra month of rest this summer in hopes of staying healthier by spring.
Duncan wore the brace for about 16 minutes while shooting 2 of 4 from the field and grabbing five rebounds. He sat for the entire second half along with Tony Parker, who scored 12 points in his preseason debut.
"It feels pretty good," Duncan said. "I've gone through four or five braces throughout the summer, trying to find the right one, the one that feels good, and that's the one I came up with so far."
Manu Ginobili added seven points as the Spurs reunited their Big Three on the court for the first time since Ginobili's season-ending ankle injury last April.
Ginobili said he's not satisfied with his game but knows he needs time. So does Duncan, he said.
"He's a little out of rhythm, too, and not playing great," Ginobili said. "But I think we're very patient with him, of course. He needs time. He needs to play probably the same way I need to play. The only one really in basketball shape is Tony, because he played all summer long."
Parker spent the offseason playing for the French national team. He gave the Spurs a brief scare when he sprained his ankle overseas, but the injury proved to be minor.
Ginobili, Parker and Duncan played with a batch of new faces. Richard Jefferson, the marquee addition for the Spurs in a busy offseason, scored four points. Antonio McDyess, who left Detroit for San Antonio as a free agent, had four points and five rebounds.
To make room for McDyess and Jefferson -- along with veterans Theo Ratliff, Keith Bogans and rookie DeJuan Blair -- the Spurs let go six players from last season's team. All 18 players the Spurs have in camp played against Olympiakos.
Sofoklis Schortsanitis, a giant 310-pounder from Greece, had 12 points for Olympiakos.
Josh Childress scored 15 points for Olympiakos, which lured the former Atlanta Hawks star with a three-year, $20 million deal last year. Starting his second season in Greece, Childress was 6 of 12 from the field and had seven rebounds.
The Hawks will again retain the NBA rights to Childress after next season, and Childress has said he was open to a return to Atlanta where he played four seasons.
Olympiakos will play a final exhibition against an NBA team on Monday at Cleveland.
