The Los Angeles County district attorney's office said Monday that they had insufficient evidence to pursue the case. A charge against Dragovic's friend, Aleksandar Stanisic, was also dropped Monday.
Authorities say Stanisic argued with another man and his girlfriend during a concert. Dragovic, a 22-year-old forward from Serbia, was accused of rushing the man and slamming him into a glass case, which shattered.
Dragovic's attorney, Jon Artz, had said the alleged victim was the aggressor in the confrontation, slapped Stanisic, threatened Dragovic and pursued him downstairs after the concert.
