The Washington Bullets, who have not won a road game since Dec. 17, hope for a remedy tonight in Houston (WDCA-TV-20 at 9:05). The Rockets, with the NBA's worst record at 5-32, have lost five straight and seven consecutive home games. The Bullets' record is 17-19, after five losses in a row.

The absence of speedy starting guards Frank Johnson (chip fracture in right elbow) and Don Collins (stress fracture in left foot) is one of the main reasons for the Bullets' longest slump of the season.

Johnson was averaging 13.6 points before he was placed on injured list Dec. 20. The last game Collins played was Christmas night against Atlanta, but his foot bothered him before then.

Johnson is again practicing in noncontact drills and is expected to return soon, but Collins probably will be out another month. The Bullets have since signed Kevin Porter and Chubby Cox at guard but the team has not shot better than 50 percent in any game since a Dec. 17 victory at Detroit, its last road victory.

Former Bullet Elvin Hayes, at 37 the oldest player in the NBA, needs 60 minutes to equal Wilt Chamberlain's record of 47,859 minutes played. Hayes' 26,341 career points leave him 54 points shy of John Havlicek, fourth on the all-time NBA scoring list. He is averaging 13.2 points, second on the Rockets to guard Allen Leavell's 13.4 points. Hayes leads the club in rebounds with 8.3 per game.
