Sony Pictures TV released a statement on Wednesday evening (June 27) saying that Trebek has made a full recovery
"I am happy to report that Alex has been released from the hospital and is back at his home," Sony spokesperson Paula Askanas confirmed.

Trebek previously suffered a minor heart attack in 2007, and recently injured his leg while chasing a burglar from his home.
