The cause of death for actor Matthew Perry, who was discovered unresponsive in his hot tub Saturday, has been deferred, the Los Angeles County Medical Examiner’s Office announced on Sunday.

Best known for his role on the sitcom “Friends,” the 54-year-old had reportedly returned home after a two-hour round of pickleball in the morning before sending his assistant on an errand, TMZ reported. When his assistant returned home, he discovered Perry unconscious.  

LAPD received the emergency call around 4:10 p.m. and first responders made their way to the home in the 18000 block of Blue Sail Drive in the Pacific Palisades.  

The circumstances surrounding the actor’s death remain unclear, although KTLA’s Omar Lewis reports police said they do not believe foul play was involved. 

Tributes to the iconic sitcom star have been pouring in from fans, fellow actors and studio executives.

His family spoke to People Magazine and in a statement and said that they are “heartbroken” by the loss of a “beloved son and brother” who “brought so much joy to the world both as an actor and as a friend.” 

“You all meant so much to him and we appreciate the tremendous outpouring of love,” Perry’s family said. 

On Sunday, many fans made their way to Perry’s Pacific Palisades home, leaving flowers at the doorstep to express their sadness and grief at his passing.

The last post Perry shared on his Facebook page was an image of him relaxing in a hot tub overlooking night views of L.A. just a few days ago. 

According to the county medical examiner’s website, a deferred cause of death means that additional investigation of the case has been requested.
