Thunder center Kendrick Perkins has had a second surgical procedure this offseason.
The club announced Thursday that Perkins underwent a successful procedure to repair a ligament tear in his left wrist.
Perkins suffered the injury in the Western Conference Finals against the San Antonio Spurs.
On July 12, the Thunder announced Perkins underwent a successful procedure on his right groin, which he initially injured during Game 4 in the opening round of the playoffs against the defending champion Dallas Mavericks.
The 27-year-old Perkins is expected to miss 4-6 weeks before returning to normal offseason activities, but he is expected to be ready for the 2012-13 season.
Perkins started 65 regular-season games and averaged 5.1 points, 6.6 rebounds and 1.12 blocks in 26.8 minutes.
