The Oklahoma City Thunder says guard Kevin Ollie underwent successful "minor" surgery Monday to relieve pain in the patellar tendon in his right knee.
Ollie has missed three games with the injury and is expected to be out up to four more weeks.
Another Thunder guard, Kyle Weaver, also had successful surgery Monday on his separated shoulder, an injury he suffered last week during practice. The team says his rehabilitation will last at least four months.
Oklahoma City center Nenad Krstic missed his first game of the season Sunday with soreness in his left Achilles tendon and forward Nick Collison missed his fourth consecutive game with a sprained knee.
Guard Shaun Livingston has been sidelined following arthroscopic knee surgery two weeks ago, but practiced Saturday and participated in the team's practice Sunday.
