Houston Rockets forward Rodney McCray agreed to terms, signing a six-year contract, and is expected to be in uniform for Friday's season opener. Terms of the deal were not released.

McCray led the Rockets in assists (434) and free throw percentage (.779) last season and set a club record for field goal percentage (.522). He averaged 14.4 points a game.

The Rockets also announced Houston has been selected to host the 1989 NBA All-Star Game, set for Feb. 12 in the Astrodome . . .

Los Angeles Clippers all-star guard Norm Nixon, who missed all of last season with an injured left knee, ruptured his right Achilles' tendon in practice and will be lost for the upcoming season.

Nixon, 32, will have surgery today and his career is in jeopardy . . .

Forward Cliff Robinson of the 76ers has rejected a two-year contract proposal and the team has pulled the offer off the table, said a spokesman for Robinson. The former Washington Bullet remained at his home in Oakland just two days before Philadelphia opens the season at the Spectrum Friday against the Indiana Pacers . . .

The Los Angeles Lakers traded former University of Maryland standout Adrian Branch to the New Jersey Nets and placed forward Billy Thompson (knee injury) on the injured list.

Branch, a 6-foot-7 swing man who signed with the Lakers as a free agent prior to the 1986-87 season, was sent to the Nets for an undisclosed amount of cash, team officials said.

Branch averaged 4.3 points in 32 regular season games and 8.7 points in preseason games this fall.

The Nets also acquired rookie Dallas Comegys from Atlanta for a second-round draft pick.

Comegys was the Hawks' first pick in this year's NBA draft and the 21st player picked overall. The Nets will send Atlanta a second-round choice in either 1989 or 1990, depending on the Nets' finish.
