John Wall has five non-displaced fractures in his left wrist and hand, and the All-Star guard's playing status has not been determined.

Wall was hurt in Game 1 of Washington's Eastern Conference semifinal series against the Atlanta Hawks. Initial X-rays were negative, but "multiple examinations" on Wednesday revealed the injuries, the Wizards announced Thursday.

Washington hosts Atlanta for Game 3 on Saturday. The top-seeded Hawks won Game 2 to even the series at 1-1.

"Obviously not the news you want to hear," Wizards coach Randy Wittman said Thursday. "With the swelling, we knew maybe there was not good news there."

Wall, who led the Wizards with 17.6 points and 10 assists per game during the regular season, was not made available to speak with reporters.

"It's definitely difficult for the team, but I'm sure it's even more devastating for John," forward Paul Pierce said.

Though he practiced following Sunday's series-opening win in Atlanta, Wall was a surprise inactive for Game 2.

Wittman didn't rule Wall out, but said, "We've got to be prepared as a team to play without him."

Butler most improved

Chicago guard Jimmy Butler was named the NBA's Most Improved Player after making his first All-Star team and averaging a career high in scoring.

"I felt like at any level I was at, whether it be junior college or Marquette, I don't think I was supposed to be there," said Butler, 25. "Somehow, some way, with the people that were in my corner, I found a way to get there."

He received 92 of 129 first-place votes and 535 total points from a panel of sportswriters and broadcasters. Draymond Green of Golden State was second (200 points) and Rudy Gobert of Utah finished third (189).

No word on Paul

Chris Paul has worked out on the court, a positive sign in his struggle to overcome a strained left hamstring, though it's not determined whether he can play for the Los Angeles Clippers in Game 3 against the Houston Rockets.

Clippers coach Doc Rivers said Thursday that "everything is going well" with the All-Star guard, but his status is unknown going into Friday night, when the series resumes at Staples Center.
