The Dallas Mavericks quietly have begun a major front office shakeup.

Senior vice president of ticket sales and services George Prokos has been suspended, multiple sources said Friday.

Prokos, who declined to comment when reached Friday, had been with the organization for 18 years and has been a friend of owner Mark Cuban's since before he bought the Mavericks in 2000.
