ATLANTA (AP) - Atlanta Hawks center Jon Koncak plans to have arthroscopic surgery after the NBA playoffs to remove bone spurs and loose particles from his left knee.

Koncak said a series of tests confirmed his suspicions about the knee, which has been sore and swollen for several weeks. ''It doesn't affect my mobility or anything like that, but it's always sore,'' he said.

Koncak suffered a partial tear of the anterior cruciate ligament in the same knee in February 1990 and missed the final 17 games of the season.

The Hawks open the playoffs Friday against the Chicago Bulls.

LAUSANNE, Switzerland (AP) - International volleyball authorities suspended Italy indefinitely on Wednesday, charging Italian Olympic officials with interfering with the national volleyball federation's administration.

The International Volleyball Federation also barred its Italian affiliate from hosting international events for four years, including the 1994 women's world championship.

The ban will be in effect until the Italian federation elects a new president and it has ''regained its full powers in relation to the Italian Olympic Committee,'' international federation spokesman Jean-Pierre Mengual said.

Italy, however, will be able to play in the the May-July World League tournament of the world's 12 best teams because television rights contracts have been signed and the tourney cannot be reorganized at short notice.

''It's not hooliganism - just folks having a laugh,'' said Craig Thompson, a 26-year-old from Airdrie, Scotland, who also braved the unseasonably cold weather in a kilt.
