The 41-year-old actor, who recently tested positive to COVID-19 was initially diagnosed with pneumonia.
He later had complications after his blood pressure increased and had a blood clot in his right leg which needed to be amputated for him to survive.
His wife, Amanda Kloots took to her Instagram page to explain and give updates on her husband’s health.
She wrote: “I received difficult news, Saturday, was day 18 of my husband being sedated in the intensive care unit at Cedars-Sinai Medical Center in Los Angeles.
“While hospitalized, he started having clotting issues on his right leg, and could not get blood down to his toes. The blood thinners he got to fix the clotting issues were affecting his blood pressure and causing internal bleeding in his intestines.
“We took him off blood thinners but that again was going to cause some clotting in the right leg, so the right leg will be amputated today
She added that he made it through surgery and hopes to recover soon.
“He made it through the surgery, which is really big,” her post read.
The Canadian actor is best known for his work in Broadway productions of Waitress and Bullets Over Broadway.
He was nominated for the Tony Award for Best featured actor in a Musical and the Drama Desk Award for outstanding featured actor in a Musical.
