Derrick Lewis, an all-Atlantic Coast Conference basketball selection last season, has been dismissed twice from the University of Maryland for academic failings, but the star center will be eligible to play this season, university officials confirmed yesterday.

"He has a 2.0 average and he's solid," said Athletic Director Lew Perkins from Raleigh N.C., where Maryland was playing N.C. State in football. "All I've got to say is that he's back in school, he's worked hard and he's ready to go."

Lewis was dismissed following the spring semesters of 1985 and 1987, but has brought his grade-point average to an acceptable level to be eligible this season, the Diamondback, Maryland's student newspaper, reported in Thursday editions.

According to the Diamondback, Lewis, a junior majoring in criminal justice, brought up his GPA after enrolling in four three-credit internship courses during the summer.

Maryland students are allowed to take up to six hours in each of the two summer-school sessions. Normally, only first-session grades count in being considered for readmission, but the rules also allow for students to request that second-session grades be considered.

Lewis, who averaged a team-high 19.6 points a game, could not be reached to comment on the report.

Eligibility standards established last spring by Chancellor John Slaughter require athletes with 72 or more credits to maintain a GPA of 2.0 on a 4.0 scale. According to the Diamondback, Lewis has a 2.0 GPA with 82 credit hours.
