Rush leaped in the air for a dunk when Randolph fouled him from behind with 4:09 left in the first quarter. Rush's left leg landed awkwardly, his knee bent badly and he tumbled to the floor.
Rush got up on one leg, waved his arms violently in the air and shook off teammates who tried to help as the announced sellout of 19,596 halted to a hush. He covered his face in agony and openly wept, eventually limping to the locker room with the support of teammate Jeremy Tyler and trainers.
"His reaction kind of said everything," Curry said.
Randolph put his arm around Rush at one point. The Grizzlies forward said he "went over there and told (Rush) I was sorry and that if he needs me, I'm there for him, whatever he needs."
Memphis selected third-string center Andris Biedrins to shoot the free throws. The home fans booed Biedrins — the former starter — when he checked in, just as they did during team introductions before the game, and he missed both free throws.
Rush signed an $8 million, two-year deal in July after coming over in a trade from Indiana last season. He had been Golden State's first player off the bench and a key cog late in games.
In the moments following the fall, the Warriors looked lost.
Quincy Pondexter's dunk capped a 24-15 spurt after Rush's injury, moving Memphis ahead by 14 points early in the second quarter. Golden State's rally expended all the energy it had left too early.
"It was another hard-fought battle," Grizzlies coach Lionel Hollins said. "Our guys were focused and had a lot of intensity, had a lot of effort. They stuck together and overcame a lot of adversity out there. It was a rock-em-sock-em game."
NOTES: Bogut is expected to sit out Saturday night at the Los Angeles Clippers. Warriors coach Mark Jackson said he plans to rest Bogut to rest when the on the second half of back-to-back games early this season to ease the center — and his surgically repaired left ankle — back into game shape. Rookie Festus Ezeli will likely start. ... Randolph also unintentionally poked Ezeli in the eye during the first quarter. The rookie center returned after a few minutes. ... A moment of silence was held before the game for the victims of Hurricane Sandy in the Northeast.
