Dallas (WBAP/KLIF) A one year old male giraffe named after Dallas Cowboy Tightend Jason Witten passed away suddenly Monday morning at the Dallas Zoo. Zoo officials say Witten was receiving a routine physical exam under anesthesia when he stopped breaking. Efforts to revive him were not successful. A statement on the zoo’s facebook page read “Our expert veterinary staff and giraffe zoologists have performed these physical exams many times in the past without incident, but for humans and animals alike, there is always a risk associated with anesthesia and some animals react differently.” The statement went on to say, “Witten captured all of our hearts with his outgoing, lovable personality and will be deeply missed. Hoofstock animals, like giraffe, are incredibly resilient and move on quickly, as they would in the wild. But we are keeping a close eye on our herd.
