CELTICS STAR'S DAD IN STAB-A-THON

Faces charges of attempted murder

Former boxing champ Marselles Brown, dad of Jaylen, in court

THE hulk-like former boxer-father of Boston Celtics star Jaylen Brown has been clobbered with attempted murder charges after witnesses say he stabbed a man repeatedly in a fight over a minor door-ding in a parking lot.

While hoopster Jaylen is 6-foot-6, he's dwarfed by his 52-year-old dad, Marselles, a 300-pound, 7-footer and former WBU heavyweight champion with a 33-18 win-loss record.
