TARPLEY OUT:

Dallas Mavericks forward Roy Tarpley will miss at least three weeks after dislocating his right kneecap early in Friday night's game against the Orlando Magic.

"It will be two weeks before he's over the soreness, with a third week for functional rehabilitation," team spokesman Tony Fay said. "So he'll be out at least three weeks."

Tarpley was carried off on a stretcher late in the first quarter of the game won by Dallas, 111-99.

A Mavericks official said Tarpley's kneecap was knocked out of place, and doctors were able to push it back in.

Tarpley, leading the Mavericks with averages of 24 points and 12.3 rebounds per game, had just scored on a fast-break layup.

When he landed, his knee buckled inward and he went down in pain.

He left the game with six points and six rebounds.

76ERS IN MOTION: The 76ers traded F Bob Thornton to the Timberwolves for a second-round pick in 1991.

Team spokesman Marty Mack said the 76ers, who have lost G Johnny Dawkins for the season with a torn knee ligament, are expected to make more moves in the next two days.

Thornton, 28, is in his fifth season and went to Philadelphia as a free agent in 1987. Previously, he had spent two seasons in Spain and two with the Knicks.

WARRIORS STUFF: The Warriors put C Mike Smrek on the injured list after he bruised ribs in practice Thursday.

Golden State activated former Houston Rockets F Jim Petersen. He had been sidelined with a bruised posterior hip.
