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)."

Play it again: The game marked the seventh in NBA playoff history to go at least three overtimes. The Bulls have played three of them, losing to the Suns in the 1993 NBA Finals and defeating the Celtics in a 2009 first-round series.

Hinrich and Joakim Noah played in the Celtics' game.

"I was younger then," Hinrich said, again laughing. "This is one of those games where they're probably going to be talking about it for a while just like everybody was talking about how that Boston series was such a great series."

Fight night: The bad blood between Nate Robinson and C.J. Watson spilled over in the second quarter when Robinson fouled Watson, who retaliated with an elbow. Robinson shoved Watson into the scorer's table and both were assessed technical fouls.

"It's just two guys being competitive," Robinson said. "C.J. brings the best out of me. But it's bigger than that. This is two teams trying to make the next round. He's going to push me. I'm going to push him."

Layups: The Bulls set playoff franchise records for points (142) and field goals (58) and became the first NBA team since 1986 to shoot 53.2 percent or better with more than 100 attempts. Their 109 shots tied another franchise playoff mark. … Robinson, Taj Gibson, Noah, Gerald Wallace and Reggie Evans fouled out and six technical fouls were assessed, including one on Bulls assistant coach Ron Adams. That's the second technical foul on an assistant this series after Nets coach Popeye Jones drew one in Brooklyn.
