The Kings will waive Okpala (knee) on Saturday, Adrian Wojnarowski of ESPN reports.
Okpala hasn't played since Jan. 28 due to bilateral knee soreness, and Wojnarowski reports that the fourth-year forward is scheduled to undergo a season-ending surgery to address at least one of the knees. Sacramento signed P.J. Dozier to a one-year contract to take Okpala's spot on the 15-man roster. Before missing time with the knee injury, Okpala made 35 appearances (three starts) for Sacramento and averaged 1.3 points, 1.0 rebounds and 0.4 assists in 7.1 minutes.
