GMINSKI TRADED:

The 76ers traded 11-year veteran C Mike Gminski, 31, to Charlotte yesterday for F Armon Gilliam and C Dave Hoppen, both 26.

The trade comes just two days after Gminski became the 162nd man in NBA history to score 10,000 points and gives the Hornets a desperately needed center.

But Gminski, a career 47-percent shooter, injured his left elbow this season and has had his shooting average plunge to less than 38 percent. In 30 games, he has averaged 9.1 points and 6.7 rebounds.

Gilliam, a four-year veteran who joined the Hornets in December 1989 from Phoenix, is averaging 19.8 points and 6.7 rebounds.

He scored more than 1,000 points in 1989-90 for the second straight season and led the Hornets in scoring 23 times and in rebounding 32 times.

Hoppen, who joined the Hornets in their inaugural 1988-89 season from Golden State, has seen only sporadic action in the NBA. He has played less than six minutes a game this season, averaging 2.3 points.

YOUNG GUN:

Rookie G Chris Jackson of the Nuggets has attempted at least 20 field goals in seven straight games, but has made only 40 percent of his shots. Jackson is averaging 16.6 shots in 23.5 minutes per game.

HONORED:

Karl Malone of the Jazz, who averaged 30.2 points and 12.5 rebounds last month, was picked as NBA player for December. Malone was 159 for 283 from the field, a .562 percentage, and led the Jazz in scoring 13 times in 15 games, including nine with 30 or more points.

NET RETURN:

Roy Hinson, out almost a year with a knee injury, was activated by the Nets for what he described as one last try at basketball. To make room for the eight-year veteran, the Nets placed rookie G Tate George on the injured list with a viral infection and dehydration.

Hinson, who had arthroscopic surgery on his right knee in February, has not played since Jan. 20. The former Rutgers star averaged 15 points and 6.9 rebounds in 25 games before aggravating the injury that caused him to miss the first 14 games of last season. . . .

Arthroscopic surgery to repair a minor cartilage tear in Heat C Rony Seikaly's knee was a success. Seikaly, the team's leading scorer and rebounder, is expected to be back in about three weeks. He tore the ligament during the Heat's Dec. 27 game in Denver. . . .

The Mavericks announced plans to sign F Howard Wright to a 10-day contract to replace injured F Herb Williams.
