Maryland basketball trainer Tommy Lyles has been relieved of his duties with the team because of differences with Coach Lefty Driesell.

Lyles, who has worked with the basketball team for the past two years, recommended that freshman Ed Farmer not play against Penn State Saturday because of a sore left shoulder. Driesell, after calling team physician Stanford Lavine, played Farmer for five minutes.

Sunday, after a coaches meeting, Driesell told Lyles he should consider working elsewhere.

Dick Dull, the school's athletic director, said yesterday he had temporarily reassigned Lyles to the wrestling team and that he would meet with Lyles today to determine his status. Lyles, a retired teacher, couldn't be reached for comment yesterday.

J.J. Bush, the football trainer, will serve as the interim basketball trainer, with assistance from Jim Weir.

Driesell said yesterday that he no longer wanted Lyles because "he's not licensed. Mr. (Jim) Kehoe (the former athletic director) assigned him as a temporary a couple of years ago, but he still isn't certified. It had been put off long enough. Tommy's a great guy, I like him, but . . . "

Driesell has been upset about the number of injuries his players have sustained and the large amount of practice time they have missed. Farmer has missed at least 10 days of practice in the last two weeks with assorted injuries, but said last week he thought he would be able to play against Penn State.

Dull said he is sure Driesell, by playing Farmer, did not violate any medical orders and that Farmer was available to play against Penn State.

Lyles is the sixth trainer in the last 13 years to have been ousted by Driesell.
