BOSTON CELTICS guard Rajon Rondo has been suspended for Game 2 of the opening-round playoff series against the Atlanta Hawks.

The NBA announced its decision Monday, less than 24 hours after Rondo stuck out his chest to bump referee Marc Davis while complaining about a call in the final minute of Boston's 83-74 loss in Game 1.

Rondo won't be able to play Tuesday night in Atlanta when the Celtics try to even the series. The NBA's assist leader scored 20 points and dished out 11 assists in the opener, leaving Boston with a huge hole in its lineup.

The Celtics already have been playing without shooting guard Ray Allen, who is hobbling on a sore right ankle. Avery Bradley likely will move over to take Rondo's place at the point.

This is Rondo's second suspension of the season, following a two-game ban in February for throwing a ball at an official.

"That's part of the package with our team. We're a volatile team in a lot of ways," coach Doc Rivers said. "Rondo is an emotional player . . . I like his fire, but sometimes he burns you."

The worst team in NBA history will have a new coach next season.

The Charlotte Bobcats have decided not to renew coach Paul Silas' contract after the team finished 7-59 this season for the worst winning percentage in league history (.106).

The 68-year-old Silas said he was not surprised by the decision. He said he was promised a job in the organization by team owner Michael Jordan.

* Los Angeles Clippers forward Caron Butler is likely out for the rest of the playoffs after breaking his left hand in Game 1 against Memphis.

* Jeremy Lin practiced with the New York Knicks, and the team said it hopes to know more later this week about when the guard might be able to return to the lineup.

Lin participated in the team's gameday shootaround before its playoff matchup with the Heat, the fourth straight day that Lin did some on-court work in Miami.

Lin had surgery to repair torn cartilage in his left knee 4 weeks ago.

* Los Angeles Lakers forward Jordan Hill faces a felony assault charge after his girlfriend accused him of choking and shoving her in Houston earlier this year.

Hill is charged with assaulting 28-year-old Darlene Luna on Feb. 29 at his apartment while the New York Knicks' former first-round draft pick was playing for the Houston Rockets. Luna told police that the two had been dating for about 2 years.
