Diamond’s health is “serious,” and he is undergoing testing at an unknown Florida hospital to determine the type and severity of the cancer, his representative said.
An actor and stand-up comedian, Diamond is best known for playing Samuel “Screech” Powers in the teen series recently reimagined by the streaming service Peacock featuring some of the original stars, but not Diamond.
His 2009 book “Behind the Bell”, in which Diamond shared backstage stories about shooting “Saved by the Bell,” caused controversy.
He also faced some legal troubles and spent three months in prison for stabbing a man during a 2014 altercation at a Wisconsin bar.
The actor has appeared on a number of reality shows over the years, including “Celebrity Fit Club”, “Celebrity Boxing 2” and “Celebrity Championship Wrestling”. In 2018 he appeared as his “Saved by the Bell” character in the series “Zack Morris Is Trash”.
