Diamond is best known for playing the role of Screech in the 1990s teen sitcom, which he starred on for several seasons opposite Lopez.
Though the show has made a comeback with the recent reboot on NBC's Peacock, Diamond was not involved in the new series.
The actor, the only one of the six core cast members to not appear in some capacity in the revival, spoke to TMZ about his absence in February.
"It's something we put so much time and effort into," the actor said at the time. "How do you have Saved by the Bell without Screech? Right? I mean, it seems like there's a missed opportunity there."
