Conan O'Brien's last night as host of The Tonight Show with Conan O’Brien will likely be next Friday, a source close to O'Brien tells PEOPLE.
"Conan does not currently plan on doing any more new shows after next week,” says the source.
According to NBC, a pre-scheduled hiatus for the program starting on Jan. 25 has been on the calendar for months.
"Everyone is working as usual in getting the show on," says a source at the Tonight Show.
On Tuesday, the host released a statement saying that he would not go along with NBC's plan for him to host a relocated Tonight Show at 12:05 a.m., following The Jay Leno Show at 11:35 p.m.
"I cannot participate in what I honestly believe is [The Tonight Show's] destruction," said O'Brien.
If Jan. 22 is indeed O'Brien's final broadcast, the show will have ended two weeks before NBC’s scheduled preemption for its 2010 Winter Olympics coverage.
