The status of guard Gus Williams remains uncertain for the Washington Bullets' next game, Thursday night against the Indiana Pacers at Capital Centre at 7:30.

Center Rick Mahorn, out three of the last four games because of a sprained left ankle he incurred Nov. 21 against Kansas City, likely will be able to play Thursday.

Williams strained the adductor tendon in the groin area of his right leg Friday in Detroit against the Pistons. A team spokesman said yesterday that Williams' availability for Thursday's game would become clearer after he is evaluated Wednesday by team physicians.

After playing 30 minutes against the Pistons, Williams missed the Bullets' last game, a 100-97 victory at home over the Milwaukee Bucks.

Williams, leading the team in scoring (20.9 average) and assists (6.2), has become an integral part of the Bullets, who have won 10 of their last 12 games for their best start since 1978-79.

Williams, acquired from Seattle during the offseason, is second in the NBA in steals this season with 48, averaging 2.67 a game. With 1,395 career steals, Williams needs nine more to pass Randy Smith as the all-time NBA leader.
