Center Darryl Dawkins shattered his second backboard of the season tonight, stopping an NBA game at the Spectrum.
The Philadelphia 76ers led the San Antonio Spurs, 110-99, after Dawkins' dunk shot with 6:43 left to play.
The 76ers came back after the delay to win, 32-120.
The 6-foot-11 center knocked the hoop cleanly off the backstop with his shot. That put a hole in the glass backboard and the glass began to shower onto the court.
Dawkins, who was alone under the basket, ducked under the falling glass. It could not be immediately learned if he was struck by any fragments.
Both teams went to their dressing rooms while workmen lowered the backstop and moved to replace the glass.
Dawkins, who weighs 252 pounds, last broke a backboard Nov. 13, early in the second half against the Kings in Kansas City.
