Oklahoma City Thunder forward Serge Ibaka is expected to miss four to six weeks after undergoing arthroscopic surgery to address soreness in his right knee, the team announced on Tuesday.
Ibaka has missed the last three games with the injury. During that stretch, Oklahoma City recorded wins over the Chicago Bulls and Minnesota Timberwolves and a loss to the Dallas Mavericks.
Over 64 games this season, Ibaka has averaged 14.3 points, 7.3 rebounds and 2.4 blocks. He is considered one of the top defensive frontcourt players in the NBA and has been named to three consecutive All-Defensive teams.
The Thunder have dealt with injuries to multiple other key players this season, including star forward Kevin Durant and guard Russell Westbrook. Durant has not played since Feb. 19 as he continues to deal with a foot injury.
Oklahoma City currently leads the New Orleans Pelicans by a half-game as the No. 8 seed in the Western Conference. The Thunder (37-30) will host the Boston Celtics on Wednesday.
