— SAN ANTONIO (AP) — The San Antonio Spurs were not going to believe Serge Ibaka was really injured until the Oklahoma City Thunder took the court in the opener of the Western Conference finals without their athletic big man.
Their skepticism was unwarranted.
Ibaka is indeed injured and Oklahoma City needs to find a way to replace his defensive presence against San Antonio.
Tim Duncan had 27 points and the Spurs took advantage of Ibaka's absence to score more than half their points in the paint, beating the Thunder 122-105 Monday night in the opener of the best-of-seven series.
Tony Parker did not appear limited by a hamstring injury, adding 14 points and 12 assists in 36 minutes in San Antonio's first victory over Oklahoma City this season.
Parker and coach Gregg Popovich both said earlier they weren't sure if the Thunder would actually be without Ibaka, who injured his left calf in Oklahoma City's series clincher against the Los Angeles Clippers.
"Contrary to what San Antonio was thinking, he's not coming back," Thunder coach Scott Brooks said.
That's bad news for Oklahoma City entering Game 2 on Wednesday.
San Antonio had 66 points in the paint and shot 58 percent from the field. It was the highest shooting percentage allowed by the Thunder in the postseason since relocating from Seattle.
The Thunder got their usual offensive output from All-Stars Kevin Durant and Russell Westbrook, who scored 28 and 25 points, respectively. But Oklahoma City's remaining starters, Nick Collison, Thabo Sefolosha and Kendrick Perkins, combined to score five points with 13 rebounds and one assist.
Collison started in place of Ibaka and was 0 for 3 from the field with three rebounds and one blocked shot.
Ibaka was averaging 12.2 points, 7.3 rebounds and 2.23 blocks in 33.9 minutes in the postseason.
"We play team defense, we don't just rely on Serge," Durant said. "He does a great job of blocking shots, but it's all because of our team defense. He's a big part of what we do. He's a starter, had his best season this year, so of course we're going to miss his presence, but we have guys that are going to step up and do it collectively."
