A source tells PEOPLE that the morning show has a general system in place.
“When Matt was on vacation or on assignment, there was a huge bench of people that filled in for him,” the source says. “Whether it’s Hoda [Kotb] or Carson [Daly] or Willie Geist or Craig Melvin, the weekend anchor.”
“There will be a rotation for now,” the source explains. “But there’s a lot that has to get worked out.”
NBC terminated Lauer, 59 after the network received a “detailed complaint from a colleague about inappropriate sexual behavior” on Monday, with reason to believe “this may not have been an isolated incident.”
Lauer, who joined the network in 1992 as a newsreader on Today, had been co-anchor of the morning show since January 1997 and reportedly signed a $20 million dollar contract last year. His termination comes after a string of firings of top stars in television news, following the ouster of Fox News’ Bill O’Reilly last April and CBS’s Charlie Rose earlier this month.

“On Monday night, we received a detailed complaint from a colleague about inappropriate sexual behavior in the workplace by Matt Lauer. It represented, after serious review, a clear violation of our company’s standards. As a result, we’ve decided to terminate his employment,” Andrew Lack, chairman of NBC News, said in a statement. “While it is the first complaint about his behavior in the over twenty years he’s been at NBC News, we were also presented with reason to believe this may not have been an isolated incident.
“Our highest priority is to create a workplace environment where everyone feels safe and protected, and to ensure that any actions that run counter to our core values are met with consequences, no matter who the offender,” he continued. “We are deeply saddened by this turn of events. But we will face it together as a news organization — and do it in as transparent a manner as we can. To that end, Noah and I will be meeting with as many of you as possible throughout the day today to answer your questions.”
A source told PEOPLE Lauer was fired after alleged inappropriate sexual behavior throughout 2014, including at the Winter Olympics in Sochi, Russia. (Reps for Lauer declined to comment.)
An NBC staffer filed a complaint Monday “that was serious enough that he was terminated,” the source explained. “The accuser described inappropriate sexual behavior in the workplace occurring throughout 2014.”
