Golden State Warriors point guard Stephen Curry received treatment on his sprained left ankle Saturday and is considered a game-time decision for Game 4 of the Western Conference semifinals.

Meanwhile, his San Antonio Spurs counterpart, Tony Parker, sat out practice Saturday with a bruised left calf, but said he would "definitely" play Sunday.

"If he goes, he goes," Warriors coach Mark Jackson said of Curry. "If he doesn't, then Jarrett Jack will be our starting point guard."

Those aren't reassuring words to Warriors fans who booed Jack and used his name in vain on the way out of Oracle Arena on Friday night. That reaction came after Jack missed a 3-pointer in a no-pass possession and threw the ball away late in the Warriors' 102-92 loss in Game 3, giving the Spurs a 2-1 lead in the series

However, Jack sounded confident Saturday that he could handle the job if asked to replace the Warriors' leading scorer and the playoffs' top assist man.

"I've done it many, many, many times," said Jack, who has started 253 regular-season and four playoff games during his eight-year NBA career. "It won't be anything [where] I've got to go in there and read a Phil Jackson Zen book or anything. I've just got to come out there and be ready to lead our team."
