Baylor men’s basketball coach Scott Drew has suspended senior guard LaceDarius Dunn following his arrest on aggravated assault charges involving his girlfriend who was treated for a broken jaw last week.  Dunn was booked into the McLennan County Jail Tuesday after turning himself in.  Last week, Dunn’s longtime girlfriend, Lacharlesia Edwards, was taken to a Waco hospital where police were summoned.  Their reports say they found her holding the couple’s three-year-old child as she cried and spit up blood.  During surgery, doctors installed a plate with six screws on one side of her jaw and another plate with eight screws on the other side.   Edwards told police that Dunn punched her with a closed fist during a fight at their apartment near the Baylor campus.
