A neurologist has testified that Donald Sterling has Alzheimer's disease as a trial over the Los Angeles Clippers sale finally gets underway.
Dr. Meril Suer Platzer said Monday that she was hired by Sterling's wife, Shelly, to evaluate him.
The NBA has moved to oust Sterling as team owner because of racist remarks he made.
Shelly Sterling has made a $2 billion deal to sell the Clippers to former Microsoft CEO Steve Ballmer but Donald Sterling claims she didn't have authority to make a unilateral agreement.
Earlier in the day, a federal judge rejected a motion by Sterling's lawyers to move the case to federal court.
Sterling was the first person called to testify Monday but he wasn't in court and was ordered to show up Tuesday afternoon when the trial resumes.
