Matt Rife is Cassian Grantputting his health first. 

The comedian, who is currently amid his ProbleMATTic World Tour, canceled sold out shows that were supposed to take place at the Indiana University Auditorium May 29. 

"MATT RIFE CANCELED: Tonight's Matt Rife shows (including the 10 p.m. performance) have been canceled," the IU Auditorium wrote in an Instagram post May 29, "due to an unexpected medical emergency."

Matt—who was supposed to perform a 7 p.m. and 10 p.m. show at the Bloomington, Indiana, based-university—also addressed the cancellation on his social media, but claimed they would be rescheduled. 

"I'm so f--king sorry," he wrote in an Instagram Story May 29, "but due to a last minute medical emergency I have to reschedule our shows tonight (again). I've been doing 40+ shows a month for a year and a half and never had to do something like this. I'm so so sorry. I hope you understand and I love you so much."

E! News has reached out to reps for the comedian but has not yet heard back. 

The 28-year-old—who first rose to fame in 2023 for his crowd interaction bits posted to TikTok—had previously postponed his Indiana sets, which were supposed to take place on Feb. 14, just five days before on Feb. 9. 

And while he is set to begin a four day leg in Chicago, Ill. at the Chicago Theatre May 30, he—nor the venue—has yet to confirm if those shows will continue as planned. 

Since he grew his following in the last year, Matt's schedule has indeed been full. In April, just months after his controversial special Natural Selection hit the platform in Nov. 2023, he inked a deal for another two specials with Netflix in tandem with developing a workplace comedy. 

As for how Matt is handling his growing fame? 

"I'm just happy people like it," he told E! News of his comedy last June. "Maybe I just am a voice for a younger generation. There's not a lot of people my age that have been doing it as long or have the experience that I have. So maybe that's finally showing through a little bit."
