Nick Gilbert, son of Cavaliers owner Dan Gilbert, is scheduled to undergo major brain surgery at a Detroit-area hospital this week, a team spokesman confirmed.

Gilbert, 21, a student at Michigan State University, was born with neurofibromatosis (NF), a genetic disorder that causes tumors to grow on nerve tissue.

The younger Gilbert’s upcoming operation was revealed by ESPN analyst Doris Burke in a shout-out to Nick during the Cavs’ victory over the Boston Celtics Sunday at TD Garden.

Gilbert became part of Cavaliers history in 2011, when he represented the team during the NBA Draft lottery as the Cavs got the No. 1 pick, which enabled them to draft Kyrie Irving. When his dad called him his hero on the broadcast, Nick responded, “What’s not to like?” His comment led to a Cavs’ marketing campaign.

Dan Gilbert serves on the boards of the Cleveland Clinic, the Children’s National Medical Center and the Children’s Tumor Foundation, which is focused on finding a cure for NF.
