The Lakers have promoted Jim Perzik from general counsel to senior vice president of legal affairs/secretary, while hiring Dan Grigsby to fill Perzik's former position.

Grigsby previously was partner and chairman of the National Sports Law Group with the law firm Jeffer Mangels Butler & Mitchell.

"Having worked with Dan as our outside legal representative for over 30 years, we’re very familiar and comfortable with him, and have the highest regard for him as both an attorney and person,” said Jeanie Buss in a statement Tuesday.

Perzik served as an advisor to the late Jerry Buss for almost 50 years, helping Buss in the initial 1979 acquisition of the Lakers.

In his new role, Perzik will continue to oversee the team's legal issues, including the development of the Lakers' new practice facility and offices in El Segundo.

Perzik will gradually reduce his workload, starting in January, but will continue to consult with the team.

"Jim has been a part of our Lakers family as well as an important member of our organization for many years," said Jeanie Buss. “His contributions to our company and our success have been invaluable and greatly appreciated."
