Kendrick Perkins (hip) exits game
The Thunder are trying to close out the defending champions in a sweep.
It's not clear when the 6-foot-10, 270-pounder injured his hip and there was no early word as to how severe the injury might be. If the Mavs win Saturday, the series will shift back to Oklahoma City on Monday for Game 5.
Perkins averaged 5.0 points and 7.7 rebounds in 27.7 minutes in the first three games and was a strong defensive presence in the paint. He left Game 4 with two rebounds and two assists in 7:51.
