Dustin Diamond, best known for playing nerdy sidekick Samuel “Screech” Powers in “Saved by the Bell,” has died, just weeks after he was diagnosed with cancer. He was 44.

“We are saddened to confirm of Dustin Diamond’s passing on Monday, due to carcinoma,” the actor’s team tells Yahoo Entertainment. “He was diagnosed with this brutal, relentless form of malignant cancer only three weeks ago.

In that time, it managed to spread rapidly throughout his system; the only mercy it exhibited was its sharp and swift execution. Dustin did not suffer. He did not have to lie submerged in pain. For that, we are grateful.”

The former child star was hospitalized less than a month ago with an unknown, but “serious” illness. Tests determined Diamond had stage IV small cell carcinoma cancer. He underwent chemotherapy.

Diamond portrayed Screech for 13 years in various “Saved by the Bell” iterations, including, “Good Morning,” “Miss Bell,” “Saved by the Bell: The New Class” and “Saved by the Bell: The College Years.” He did not reprise the role in NBC’s recent reboot. The actor also appeared in a handful of reality television shows: “Celebrity Fit Club,” “The Weakest Link,” “Celebrity Boxing 2” and “Celebrity Big Brother.” He toured as a stand-up comedian for more than a decade.

Diamond made headlines off-screen, too. He served three months in jail for stabbing a man during a 2014 bar fight in Wisconsin and faced other legal troubles. In 2006, he released a sex tape. He later revealed he was embarrassed over that decision and said it actually featured a stunt double.

The actor’s management team, who worked with Diamond for 21 years, note in Monday’s statement he was never “intentionally malevolent.”
