As the Oklahoma City Thunder work through the second half of the season, they'll be doing much of it without center Kendrick Perkins.
The Thunder announced Tuesday that Perkins had successful surgery on his left groin. He's expected to miss six weeks.
Perkins has appeared started 54 games and averages 3.4 points, 5.0 rebounds and 1.1 assists in 19.7 minutes per game.
Perkins injured his groin in the third quarter of the Feb. 20 game against Miami, the same game that Russell Westbrook returned. Westbrook missed almost two months after undergoing surgery on his left knee in late December.
