The Dallas Mavericks have split with general manager Gerrson Rosas just 3 months after Rosas was hired, according to ESPN's Marc Stein.

The 35-year old Rosas was hired away from the Houston Rockets this summer, after rising through their ranks to become the vice president of basketball operations.

The Mavs GM position has not been filled since Don Nelson left the role in 2005, but his son Donnie Nelson has handled the duties generally associated with the position until Rosas was hired.
