Johnson's first assignment will be the Christmas Day game between the Clippers and the San Antonio Spurs at the Sports Arena, NBC's first telecast of the season. Johnson will be teamed with Jim Lampley and Steve Jones.
On most other telecasts, Johnson will work with Marv Albert and Mike Fratello.
NBC's coverage of Friday's 12:30 p.m. game at the Sports Arena will begin at noon with "NBA Showtime."
The pregame show, with Lampley, newcomer Bill Walton, Quinn Buckner and Peter Vecsey, will originate from the Sports Arena.
