Kirk Hinrich drew his fifth foul with 5 minutes, 39 seconds left in regulation Saturday. He never came out again, avoided his sixth and tied John Salmons' franchise playoff record with 59:36 of playing time. "It was pretty grueling," Hinrich said with typical understatement. His extensive workload came on a left calf muscle sore enough that he needed a postgame MRI. Results weren't immediately available, but Hinrich said the injury "is pretty bad." Given his grittiness, Hinrich will play in Game 5 on Monday if at all possible. His 18 points and 14 assists marked his first playoff double-double since May 2007, and his assists tied the franchise playoff mark shared by Michael Jordan and Sam Vincent. "He's unbelievable," coach Tom Thibodeau said. Switching Jimmy Butler onto Deron Williams at times helped Hinrich avoid fouling out. "I don't know what overtime we started doing that," Hinrich said, laughing. "I was just able to stay away from (the sixth foul)."
