NEW YORK — We could soon learn what the NBA plans to do with Los Angeles Clippers owner Donald Sterling.

The league has called a news conference for this afternoon to make an announcement about the investigation involving Sterling and those racially charged comments attributed to him. And the controversy is now hitting the Clippers in the pocket book as several corporations have pulled their advertising.

Sterling is being investigated over allegations he made racially charged comments in a recorded conversation with a woman. Portions of that conversation were released over the weekend by TMZ and Deadspin.

The players' union has asked Commissioner Adam Silver to rule quickly, preferably before the Clippers play host to Golden State in the fifth game of their playoff series tonight.

Clippers coach Doc Rivers said in a conference call Monday that he opted out of a chance to speak with Sterling. Rivers also said that he believes Sterling made the comments.

Rivers says he believes "a very strong message" is coming from the NBA in response to the scandal, adding that "I can't tell you how upset I am."

The Miami Heat showed support for the Clippers' players and coaching staff before Monday's game in Charlotte.

Like the Clippers did on Sunday, the Heat ran out of the tunnel wearing their warmups, huddled at center court and tossed their white shooting T-shirts to the ground. They then went through their pregame routine with their red Heat warmup jerseys inside out, hiding the team's logo.

UNDATED (AP) — The top-seeded Indiana Pacers are in serious danger of becoming a first-round casualty in the NBA playoffs.

The Atlanta Hawks own a three-games-to-two lead after six of their players scored in double-figures during a 107-97 win over the Pacers in Indiana. Mike Scott made five 3-pointers during a 30-6 second-quarter run and ended up with 17 points. Shelvin Mack came off the bench to contribute team highs of 20 points and five assists. Paul Millsap finished with 18 points, and Kyle Korver shot 5-for-10 from 3-point range in scoring 16 points.

The Pacers outscored the Hawks in three of four quarters, but Atlanta took control by outscoring Indiana 41-19 in the second period to take a 21-point lead into intermission.

Paul George had a game-high 26 points for the Pacers, who will try to stave off elimination Thursday in Atlanta.

The Miami Heat have completed a four-game sweep to advance to the NBA's Eastern Conference semifinals.

LeBron James scored 31 points and had nine assists as the two-time defending champions ousted the Bobcats 109-98 in Charlotte. James scored 19 points after injuring his thigh in the third quarter.

Chris Bosh finished with 17 points and Dwyane (dwayn) Wade added 15 in the Heat's 20th consecutive win over Charlotte.

Miami is 16-2 in first-round games since James' arrival four years ago.

San Antonio has squared its series with Dallas at two games apiece by knocking off the Mavericks 92-88. The game was tied at 87 until Boris Diaw (DEE'-ow) hit a 3-pointer with 32.9 seconds remaining. Manu Ginobili (MAN'-oo jih-NOH'-blee) iced the victory by hitting three of four free throws in the final 10.4 seconds.

Ginobili finished with a team-high 23 points, Diaw had 17 and Tim Duncan added 14 and 10 rebounds.

Monta (MAHN'-tay) Ellis had 20 points for the Mavs, who never recovered after getting outscored 32-13 in the second quarter.

Game 5 is Wednesday at San Antonio.

MIAMI (AP) — Hall of Fame basketball coach Jack Ramsay has died. His death, at 89, was announced by ESPN, where he worked as a broadcaster until last season. No cause of death was immediately given, though Ramsay had battled cancer for many years and was placed in hospice care late last week.

Ramsay, known as "Dr. Jack" throughout the league, coached in the NBA for parts of 21 seasons, including leading Portland to the 1977 NBA title. He then began a long career as one of the league's most revered radio and television analysts.

Ramsay also was an accomplished college coach at Saint Joseph's in Philadelphia, taking the Hawks to the 1961 Final Four.
