More big changes are coming to NBC's "Saturday Night Live." 

As the long-running sketch comedy series embarks on its 48th season

USA TODAY has learned that cast members Alex Moffat, Melissa Villaseñor and Aristotle Athari won't be returning to the show this fall. 

Executive producer Lorne Michaels made the changes as he auditions potential new cast member

this week to join the show when it returns in early October.

Moffat joined "SNL" as a featured player in 2016 before being promoted to a main cast member in 2018.

The Chicago native became known for playing Eric Trump and a "Guy Who Just Bought a Boat" on Weekend Update.

He will next appear in Apple TV+ comedy "Bad Monkey" with Vince Vaughn and Michelle Monaghan.

It's believed to be the biggest cast shakeup in more than 40 years, during a period when Michaels left the show and most of the original cast was replaced.

Strong will also be absent for at least the early part of the upcoming season.
