The former Saturday Night Live star, 52, recently came down with streptococcus, a severe case of pneumonia, and was rushed to the hospital Saturday.
He reportedly underwent an emergency surgery, which was successful, and is scheduled to be released on Friday.
Following the news, Kattan’s girlfriend Maria Libri shared a photo of the two on Instagram, wishing him a quick recovery.
Kattan previously spoke about his health in 2017, detailing a life-changing injury that resulted in a 20-year recovery.
Kattan was advised he might become paralyzed if he didn’t have surgery as soon as possible, so he had a minor procedure to try and fix his neck.
Though it was a “noninvasive” surgery, Kattan still had to spend weeks in the hospital and follow up with physical therapy.
Kattan was advised to spend up to six months in recovery, but he returned to work just after just 60 days. As a result, the comedian spent the following years undergoing multiple surgeries as his recovery became challenging.
