Anderson, #4-ranked prospect in the national class of 2012 that has signed a National Letter of Intent for UCLA, was told by a physician that he will need surgery.
His father has said they will seek a second opinion.
The injured thumb is on Anderson's non-shooting hand. If he did proceed with surgery, the recovery is thought to be three months.
That means, if Anderson had the surgery soon, he'd be able to begin playing again at full capacity by the beginning of August. He could, too, continue conditioning and other work in the three-month recovery.
Practice doesn't begin until mid-October.
