PORTLAND, Ore. (AP) — Oklahoma City forward Serge Ibaka will miss the Thunder's game against the Portland Trail Blazers on Sunday night because of a chest contusion.
Thunder coach Scott Brooks says Ibaka will be replaced in the starting lineup by Nick Collison.
Ibaka had not missed any games previously this season, and was averaging 14.3 points and 8.4 rebounds.
The 6-foot-10 Ibaka was injured in the third quarter of Oklahoma City's 116-101 victory over the Los Angeles Lakers on Friday night.
