OAKLAND, Calif. -- Golden State Warriors All-Stars Stephen Curry and Klay Thompson are questionable for Game 1 of the team's Western Conference semifinal series against the Houston Rockets due to right ankle injuries, according to coach Steve Kerr.

"He's OK," Kerr said Saturday of Thompson. "He and Steph both came in this morning to get some treatment. And I haven't even spoken with [director of sports medicine and performance] Rick [Celebrini] yet today, so we're upstairs watching film and getting ready. We'll see how they're doing [Sunday]. I'm not going to make a definitive statement on whether they'll both play. Let's just call it questionable. And there's nothing implied there. They both came in today and got some work, and we'll see how they're doing [Sunday]."

An MRI on Thompson's ankle returned clean on Saturday night, league sources told ESPN's Adrian Wojnarowski.

There's optimism that Thompson will play Game 1, sources told Wojnarowski, but the bigger question is whether there will be limitations on his mobility.

Curry turned his right ankle toward the end of the first quarter of Friday's series-clinching victory over the LA Clippers. He went to the Warriors locker room to get it checked out before returning but was limping as he walked into the postgame news conference.

Meanwhile, Rockets guard Austin Rivers is out for Game 1 with an illness. Rivers had success defending Curry during the regular season. Per Second Spectrum, Curry was 11-of-31 from the floor (2-of-16 from 3-point range) when defended by Rivers.

Kerr acknowledged that Thompson's sprain, which came in the third quarter Friday, is more severe than initially thought.

"It was a significant sprain," Kerr said. "He was limping last night. So as I said, we'll see how he's doing [Sunday]."

Thompson admitted after Friday's game that the ankle was "sore" but said he was confident he would be ready for Game 1 against the Rockets.

"I anticipate going fully on Sunday, so it'll be all right," Thompson said immediately after the game.

For his part, Kerr isn't concerned about his team's focus or energy entering the series. The Warriors wish they could have taken care of business sooner in the first round, but Kerr said his team is more prepared for the Rockets series because it had to grind through a tough Clippers squad.

"I think they're more energized that we're here," Kerr said of his team. "I think we are happy to get past the Clippers; they were fantastic. They prepared us well for this series. I'm not worried about the energy because here we are, it's the playoffs, and no matter what we do, at max there's six weeks left in the season. At minimum there's a couple weeks, so we're near the finish line. So our guys are going to have plenty of motivation, plenty of energy.

"I'm more worried about the nagging injuries right now from [Friday] night, so we'll see what happens."
