Diamond, who played Screech on the NBC sitcom, died Monday.
The actor, who played "Screech" on the sitcom, was diagnosed with cancer a few weeks ago.
The actor who played Screech is undergoing treatment in Florida.
A spokesperson for the actor who played Screech said tests were being done and "it doesn't look good."
"He had his journey," the "Saved by the Bell" star told Andy Cohen before the reboot airs with the whole gang except Diamond.
He will serve a four-month jail sentence.
He played an innocent high school student in one of our favorite ‘90s sitcoms, but now he’s all grown up and apparently stabbing people.
